Cumulus.ini (preserving history)

Initial Configurations

The main cumulus.ini configuration file is located in the directory in which you installed Cumulus.exe. It is a text file containing initialization parameters used by the Cumulus application, and is read only when Cumulus starts up. Cumulus re-writes the contents of the application configuration screens to the file when it shuts down.

A second cumulus.ini may be stored in the reports sub-directory, this only contains a single section and relates to the screen used for NOAA reports.

The parameters listed can change the look of Cumulus, hold basic information about your location, amend the way Cumulus interfaces with your weather station, and hold the settings used to interface with your website and various external websites.

If you are using an old version, then checking the release information may be advisable to identify the sections applicable to your build and the parameters allowed within those sections may be a subset of those listed below.

File Structure

The main file consists of a number of sections, each with a heading delimited by '[ ]', (although the order in the file may be different to that in this article). Parameter lines are in the form 'attribute=value' and grouped by those sections.

Some sections relate to the external websites that Cumulus can optionally supply with updates. These are set by configuration screens and the whole sections will always be present. If you do not use those external services their parameters will be set to the defaults.

Each new version of cumulus may add additional parameters set by revised configuration screens (these initially appear at the end of the relevant section), and/or permit additional parameters to be added manually (these can be inserted anywhere within the section).

Beta builds

If you are using a beta build, there may be changes to the information shown below with additional sections and/or additional parameters (attribute=value) under test. Brief details of such changes will be given in the support forum annoucement for the relevant build. New sections and/or attributes and/or values for beta versions of Cumulus are not listed here until the version becomes 'live' however there is a page that details the additional parameters available in the Beta version once they have become established, but for details of beta tests see the forum.

Editing the file

Initialisation

When Cumulus is run for the very first time, the Station settings screen within the Configuration menu is displayed, so that the basic minimum settings can be entered into Cumulus.ini. Should you accidentally delete Cumulus.ini this would happen again, so it is always best to take a backup of the complete Cumulus directory and sub-directories so nothing is lost in such a situration.

See Setup for further advice, noting in particular that some settings (such as units, date/time formats) should stay unchanged.

Settings controlled by application

Many configuration parameter lines are changed from the various application edit, view, or configuration screens, and so making any amendments using those screens should ensure your replacement values are acceptable. You should never edit these parameter lines directly in the file while Cumulus is running, as when Cumulus shuts down it will replace your amendments to these parameters with the contents of the relevant application Edit/View/Configuration screens.

You can edit them in the file with Cumulus stopped, but beware of selecting invalid values for these parameters, generally it is safer to use the application to edit them (unless you are importing values from another setup), and Cumulus will read the new values when it is next restarted.

Settings independent of application

Some configuration settings can only be applied by editing this file to insert a new parameter line; they do not appear anywhere in the configuration screens. Cumulus does not write these values back out to the file on shut down, so they do not appear with default values - in other words, you need to add them if you want to set them. Make sure you place these additional parameters in the correct section as listed below.

Editing outside Cumulus

• It is best to take a copy of the existing cumulus.ini file before you make any changes (either by using application screens or by editing the file), so you can return to the original if necessary.
• If your system is configured to use a comma for a decimal separator, then you should use a comma in any decimal values that you set in this file.
• You should use a text editor (not a rich text editor nor word processor) to edit this file as only letters, numerical digits, decimal separators and the equals symbol are allowed in any parameter. If you use a spreadsheet program to make use of the manipulation it offers, ensure it is set to output in pure text.
• The parameter lines (attribute=value) can be in any order, but must be in the correct section. You might find it helpful to sort the attributes within a section into alphabetical order, to ensure you have no duplicates and to make it easier to find the particular parameter line you may wish to edit in the future.

File Contents

Introduction

The entries shown in the 'parameter line entry' column include the default value from the configuration screen where applicable, a typical example value where appropriate, or just the attribute and an equals sign where there is no typical value.

Section: Station

See individual parameters for specific instructions on setting them. In many cases this is by using Station Configuration Screen, but if the parameter line does not exist in your file, then insert it using a file editor as per instructions above.

Parameter Line Entry	Function
[Station]	Section name - the following parameters relate to the station configuration.
Type=-1	Station Type as set by the checked radio box in the Station Configuration Screen, Station Type block. For details of Supported_Devices click that link. 0=Vantage Pro 1=Vantage Pro2 2=WMR-928 3=WM-918 4=EasyWeather (using .dat file) 5=Fine Offset/Watson/MyDel etc 6=WS2300 7=Fine Offset with Solar Sensors 8=WMR100 9=WMR200
Model="your Model description"	The weather station model description - you choose what text appears for this on (from version 1.9) 'Display' settings screen within Configuration menu - the field is at the bottom left of that screen).
Port=0	Com port in your computer which is connected to your weather station if connected via a serial port. Defaults to port 0.
Latitude=0	You are advised not to directly edit this parameter in the file, but to type Latitude (unsigned) Degrees, Minutes, Seconds and select 'N' or 'S' in the Station Configuration Screen Location block. Value in this parameter is Latitude in Decimal Degrees based on what you have entered, Positive for North, Negative for South
Longitude=0	You are advised not to directly edit this parameter in the file, but to type Longitude (unsigned) Degrees, Minutes, Seconds and select 'E' or 'W' in the Station Configuration Screen Location block. Value in this parameter is Longitude in Decimal Degrees based on what you have entered, Positive for East, Negative for West
LatTxt=	You are advised not to directly edit this parameter in the file, but to type Latitude Degrees, Minutes, Seconds in the Station Configuration Screen Location block. Latitude in text string format of hemisphere D, M and S. HTML ampersand codes are used for spaces and unit characters.
LonTxt=	Longitude in text string format of hemisphere degrees, minutes and seconds. HTML ampersand codes are used for spaces and DMS characters.
Altitude=0	your station altitude as entered in the Station Configuration Screen Location block. See Cumulus Help for that screen.
AltitudeInFeet=1	Altitude measurement unit as set in the Station Configuration Screen Location block. 0 = metres Above Sea Level 1 = feet ASL
Humidity98Fix=0	Selected in the Station Configuration Screen Settings block. 0 = Disabled (default) 1 = Enabled, humidity displayed and recorded as 100% if your sensor registers a relative humidity of 98% or greater. Normally only useful for Oregon Scientific stations.
Wind10MinAverage=0	Selected in the Station Configuration Screen Settings block. 0 = Disabled (default) 1 = Enabled, Cumulus will calculate and display a 10-minute average wind speed instead of using the value supplied by the station.
CalculatedDP=0	Selected in the Station Configuration Screen Settings block. 0 = Disabled 1 = Enabled, Cumulus will calculate the dew point instead of using the value supplied by the station. This avoids the restriction in the Oregon Scientific stations where the dew point can never be below freezing point.
CalculatedWC=0	Selected in the Station Configuration Screen Settings block. 0 = Disabled 1 = Enabled, Cumulus will calculate the wind chill instead of using the value supplied by the station. Note that some stations (Fine Offset, for example, do not supply a wind chill value anyway, so Cumulus always calculates it). You should set this if you have specified any calibration values for wind or temperature, so that Cumulus can also apply those values to the wind chill.
UseWindChillCutOff=1	Calculate Wind chill only if temperature less than 10°C rule. 0 = Disabled (default) 1 = Enabled, this line needs to be added in the [Station] section of the Cumulus.ini Note that CalculatedWC=1 is needed for this setting to have any effect (if your station is a type that supplies wind chill itself); i.e. you need to set Cumulus (see directly above) to calculate the wind chill if it is to apply a rule based on temperature.
ChillHourThreshold=45	The temperature threshold is specified in the units that you use in Cumulus (see Heat/cold_degree_days_and_Chill_hours)
ChillHourSeasonStart=10	The season start figure is the calendar month number (1 to 12)
RolloverHour=0	Log roll over time as selected on the Station Configuration Screen 0 = midnight 9 = 9am/10am
Use10amInSummer=1	Daylight saving correction for 9am roll over 0 = Use 9am in summer (use 10am not checked on Station Configuration Screen) 1 = Use 10am in summer selected on Station Configuration Screen
SnowDepthHour=9	This line needs to be added in the [Station] section of the Cumulus.ini, it is the Snow lying/falling roll over time (time when yesterday's values in log.xml are forgotten) - Allowed values are 0 to 23 and represent the time to the nearest hour that snow depth measurements are taken. 0 = midnight (default) 9 = 9am, 13 = 1pm etc. Note this time is independent of your rollover time selections in the two preceding parameters.
ConfirmClose=0	Confirm you wish to close Cumulus application after telling it to close 0 = Disabled, application will close immediately 1 = Enabled, application will prompt for confirmation that you wish to close it (do not use this if you might suspend/standby/hibernate your computer)
CloseOnSuspend=1	If this is selected, on the Station Configuration Screen, Cumulus will close if you suspend/standby/hibernate your computer. You should not select 'Confirm shutdown' if you use this option. 0 = Disabled, application will not close if you suspend/standby/hibernate your computer (it is highly recommended you close Cumulus manually before your computer is put into suspend/standby/hibernate state) 1 = Enabled, application will close on suspend/standby/hibernate of your computer (recommended if your computer can go into any of these states when left alone)
DataLogInterval=2	Data log interval as selected in the Station Configuration Screen Data log interval block 0 = 1 min 1 = 5 mins 2 = 10 mins 3 = 15 mins 4 = 20 mins 5 = 30 mins Note: This can be set to match your station logging interval, then if you restart Cumulus and if Cumulus is able to read logged data from your station the frequency of logged information in your Monthly_log_files will be unchanged between the periods Cumulus is running and the periods when it is stopped. Some Cumulus users set their station logging interval at a longer time so that the station does not overwrite the memory locations over the longest period they might be away from it, but this Cumulus logging interval to be one of the two shorter times so they retain the maximum measurement detail in case of any need to correct rogue measurements.
WindUnit=0	Wind speed measurement unit Cumulus records in as selected in the Station Configuration Units block 0 = m/s 1 = mph 2 = km/h 3 = kts
PressureUnit=0	Pressure_Measurement unit Cumulus records in (as selected in the Station Configuration Units block) 0 = mb 1 = hPa 2 = in These are the labels that Cumulus applies on its screens and web pages, most weather stations work in one unit (e.g. hPa for Fine Offset) and so the values are converted to any of the 3 listed during processing
RainUnit=0	Rain_measurement unit Cumulus records in (as selected in the Station Configuration Units block) 0 = mm 1 = in
TempUnit=0	Temperature measurement unit Cumulus records in (as selected in the Station Configuration Units block) 0 = Celsius 1 = Fahrenheit
LocName=	Location Name (as entered on the Station Configuration Screen)
LocDesc=	Location Description (as entered on the Station Configuration Screen)
StartDate=13/08/2009	By default this will be set to the date of initial installation of the Cumulus application. See Monthly_log_files#Importing_pre-Cumulus_data
LastLoggerDownload=13/08/2008 12:48:52	The date/time of the last down load from your weather station (note: no longer used); see <#LastDataReadT> and Timestamp
YTDrain=0	Year to date correction if starting part way through year as entered in the Station Configuration Screen. Value is entered in your current Rain_measurement units. Default is 0.
YTDrainyear=0	The year for which the YTDrain is to be applied. Default is 0 meaning not applied to any year.
UseDataLogger=1	If selected, at start-up, Cumulus will download data from the stations data logger (if it has one) to catch up from the point where Cumulus was last shut down. 0 = Disabled 1 = Enabled (Default)
UseCumulusForecast=0	From the Station Configuration Screen Forecast block, if selected Cumulus will generate a simple weather forecast, if your station does not supply one, or as an alternative to the one supplied by your station. See the Forecast webtag for more information. 0 = Disabled (default) 1 = Enabled
UseCumulusPresstrendstr=0	Set in the Station Configuration Screen Settings block. If selected Cumulus will generate the name for the current pressure trend, e.g. "Falling", "Rising quickly" etc, instead of the one supplied by your station. The names used are those in the UK Shipping Forecast. Note that some stations do not supply this anyway, so setting this has no effect (Cumulus always generates the names for those stations). 0 = Disabled 1 = Enabled
FCpressinMB=1	Forecast pressure unit as selected in Station Configuration Forecast block 0 = inches 1 = mb
FClowpress=950	Low Pressure extreme limit as entered in the Station Configuration Forecast block. Default is 950mb
FChighpress=1050	High Pressure extreme limit as entered in the Station Configuration Forecast block. Default is 1050mb
UseZeroBearing=0	Set this in the Station Configuration Screen Settings block. 0 = Disabled, Cumulus displays the current bearing read from the station (i.e. the last direction the wind was blowing from before it became calm). Note that the average wind bearing will always display zero bearing if there has been no wind for the last 10 minutes, as the average bearing takes wind speed into account. 1 = Enabled, Cumulus display a bearing of zero (and '---' for the compass point) when the wind is calm
WarnMultiple=0	Multiple Instances of Cumulus running on PC 0 = Disabled, (default) Multiple instances allowed. 1 = Enabled, prevents multiple instances of Cumulus from running. Requires a Cumulus restart to take effect.
CloudBaseInFeet=1	Cloud base measurement unit 0 = metres 1 = feet (default)
RTdisconnectcount=N	By default, the 'realtime' ftp connection stays connected. You can make it disconnect periodically by adding an Option to periodically disconnect the realtime FTP connection, the theory being that it will not get stuck if the server dies, and will keep trying to reconnect. N must be a positive integer. For example set N to '60'; it represents the number of realtime ftp uploads between disconnections - so 60 would give an hour if 1 minute realtime interval selected.
Logging=1	Add to cumulus.ini [Station] section to have Cumulus start with debug logging on
AvgSpeedMinutes=N	where N is the number of minutes over which Cumulus calculates its average speed, if you have Cumulus set to do this. Default = 10. If you selected 60, then Cumulus would calculate rolling 60-minute average wind speeds.
AvgBearingMinutes=N	where N is the number of minutes over which Cumulus calculates (by treating the wind as a vector and taking into account the speed as well as direction) its average bearing. Default = 10.
ListWebTags=1	Add this entry to make Cumulus create (each time it is restarted) a file called webtags.txt that contains an unsorted list of all the webtags that Cumulus supports
RestartIfDataStops=0	Option to restart Cumulus if data stops. This may fix whatever the problem is; it may not. But it should at least stop the same data being repeatedly logged. 0 = Disabled (default) 1 = Enabled
ReportDataStoppedErrors=0	Option to turn off reporting of 'data stopped' errors to the Cumulus error log (may be needed with La Crosse stations) 0 = Disabled (default) 1 = Enabled
RainSeasonStart=1	The month of the year that is used as the start of the annual 'rain season'. Default = 1 = January.
RainDayThreshold=-1	The threshold value which the daily rainfall has to equal or exceed for the day to be considered a 'rain day'. Default -1 = 0.2mm or 0.01in. Value is entered in your current Rain_measurement units.
NoFlashWetDryDayRecords=1	When set to 1 stops new Longest Wet/Dry Period records being 'flashed'
UseSpeedForAvgCalc=0	When enabled (=1) Cumulus will use the longer-term 'speed' values in the average speed calculation. The 'Use 10-min average wind speed' option must be selected for this option to have any effect.
HourlyForecast=0	If Cumulus is set to generate a forecast, this setting (=1) causes the forecast to be updated only once an hour (on the hour).
RoundWindSpeed=0	When set to 1, this setting causes wind speeds rounded to the nearest integer.
ErrorLogSpikeRemoval=0	??keeps the number of messages in the error log window to a maximum of 256?
UVdecimals=1	UV values are now displayed and logged as whole numbers by default. You can change this by adding this entry specifying the number of decimal places. 0 = Integer Values (default) n = Number of decimal places
NoSensorCheck=1	The option (for 'incomplete' stations) to disable the sensor check described in this FAQ 0 = Sensor check enabled (default) 1 = Sensor check disabled

Davis family specific:

Parameter Line Entry	Function
[Station]	Section name - the following parameters relate to the station configuration.
ForceVPBarUpdate=0	Set this in the Station Configuration Screen Settings block. Select to force the Vantage Pro (and Pro2) barometer to update once a minute instead of the default 15 minutes. Note that you may not need this, more recent stations already update every minute 0 = Disabled 1 = Enabled
SyncDavisClock=0	When set, at start-up, Cumulus will set the Davis VP/VP2 clock to the same time as the PC 0 = Disabled, default as deselected on the Station Configuration Screen 1 = Enabled
VP2ConnectionType=0	Weather station connection type as selected in the Station Configuration Screen VP type block 0 = serial 1 = usb 2 = TCP/IP
VP2TCPPort=22222	Set this in the Station Configuration Screen VP2 TCP/IP Settings block. Comunications port used if VP type has TCP/IP selected. Default is 2222
VP2IPAddr=0.0.0.0	Set this in the Station Configuration Screen VP2 TCP/IP Settings block. Weather station IP address if VP type has TCP/IP selected. Default is 0.0.0.0
VP2SleepInterval=x	where x is sleepinterval in milliseconds. See note in readme.txt about VP2SleepInterval - in current release it is around line 50. This parameter (attribute=value) is added directly to the file, it does not appear on a configuration screen. See FAQ#My_Davis_station_shows_a_higher_maximum_wind_speed_than_Cumulus This is the period which Cumulus waits between reads of the data from Davis stations. The default is 500 ms; if you suspect that data is being missed, you could try reducing this figure. For VirtualVP users, tests revealed that VP2SleepInterval = 1100 seems to work the best. It updates every two seconds with few exceptions.
VPClosedownTime=x	where x is the number of seconds after the start of the re-connect attempts that you want the program to close itself. This parameter (attribute=value) is added directly to the file, it does not appear on a configuration screen.
VP2PeriodicDisconnectInterval=0	Set this in the Station Configuration Screen Settings block with the Discon period value. Causes Cumulus to disconnect for the specified number of seconds, once a minute, on the minute (or as close as possible) to allow the Weatherlink IP to connect to the Davis Weatherlink site. Set it to zero to disable, if you are not using the Weatherlink site.
DavisCalcAltPress=1	Davis stations calculate Sea Level Pressure from Station Pressure using a formula based on several parameters such as temperature, humidity, etc, rather than just using altitude as most other stations. CWOP require 'Altimeter Pressure' to be uploaded, i.e. a value calculated simply using altitude. The station does not provide this value directly, nor the station pressure, so Cumulus has to read some extra data once a minute in order to do the calculation. This can take several seconds, so it means that a 'normal' data reading may be missed. If you don't use CWOP, or you are happy for Cumulus to send Sea-Level pressure to CWOP (the difference is small unless you are at high altitude), set this value to 0. Cumulus will then use the Sea-Level Pressure value instead of the Cumulus calculated Altimeter Pressure. 0 = Disabled 1 = Enabled (default)
LogExtraSensors=0	This is set in the settings frame on the Station settings screen off the configuration menu. Set this to 1 if you have additional sensors (e.g. a Davis Leaf Wetness probe) to make Cumulus read, display, and log the readings from the sensors. You don't need to select this for Solar/UV sensors.

Introduced for problems with Fine Offset family, but may be more widely applicable:

• Note that spike removal correction may be implemented for La Crosse stations using the EW filter settings below.
• As Cumulus does not check station type before applying any of these settings, ensure for Davis stations (these do not have spike problems) the spike removal filters are set to the defaults shown below.
• Stations not recognised by Cumulus may be set to create an EasyWeather_Format file requiring the first two parameters below.

Parameter Line Entry	Function
[Station]	Section name - the following parameters relate to the station configuration.
EWInterval=0	Easyweather logging interval in minutes as entered in the Station Configuration Screen Settings block. Default is 0 meaning not applicable (as not reading observations from Easyweather software output).
EWFile=	Easyweather.dat file path/name as entered in the Station Configuration Screen Settings block.
RestartIfUnplugged=0	Cumulus will restart if it detects that a Fine Offset station is unplugged. 0 = Disabled, default i.e. deselected on the Station Configuration Screen 1 = Enabled as selected on the Station Configuration Screen
EWpressureoffset=x.y	Got a pressure problem with a Fine Offset station when the pressure 'offset' that Cumulus reads is garbage, so Cumulus just uses zero? Tell Cumulus what offset to use, by using an external text editor to insert this parameter where x.y is the difference between your station (absolute) and sea-level (relative) pressures, in mb/hPa.
EWminpressureMB=900	Cumulus will ignore all pressure readings from the station that are less than this value (units are always hPa/millbars)
EWmaxpressureMB=1200	Cumulus will ignore all pressure readings from the station that are greater than this value (units are always hPa/millbars)
EWmaxHourlyRain=999	An hourly rain rate 'spike removal' filter for weather stations that do not supply rain rate so cumulus has to calculate it; changes in calculated value greater than the value specified here (set in calibration screen of configuration menu) will be ignored by Cumulus when it calculates the rain rate. Cumulus ignores this parameter for other makes of weather station that supply a rain rate to Cumulus.
EWmaxRainRate=999	A rain rate 'spike removal' filter, changes in calculated value greater than the value specified here (set in calibration screen of configuration menu) will be ignored by Cumulus when it calculates the rain rate. Cumulus ignores this parameter for other makes of weather station that supply a rain rate to Cumulus.
EWgustdiff=999.0	A wind gust 'spike removal' filter, changes in calculated value greater than the value specified here (set in calibration screen of configuration menu) will be ignored by Cumulus
EWwinddiff=999.0	A wind speed 'spike removal' filter, changes in calculated value greater than the value specified here (set in calibration screen of configuration menu) will be ignored by Cumulus
EWpressurediff=999.0	A pressure change 'spike removal' filter, changes in read value from any station greater than the value specified here (set in calibration screen of configuration menu) will be ignored by Cumulus
EWTempdiff=999.0	A temperature change 'spike removal' filter, changes in read value from any station greater than the value specified here (set in calibration screen of configuration menu) will be ignored by Cumulus. Replace 999.0 with the maximum difference in degrees C you are prepared to accept between successive data readings
EWhumiditydiff=999.0	A humidity change 'spike removal' filter, changes in read valuefrom any station greater than the value specified here (set in calibration screen of configuration menu) will be ignored by Cumulus
EWduplicatecheck=0	Add this line to cumulus.ini [Station] section if application gets stuck in the download stage.
SyncFOReads=1	Specifies the Fine Offset synchronisation mode of operation. 0 = default 1 = Re-synchronizes each day
ReportLostSensorContact=0	Option to turn off reporting of 'lost sensor contact' for Fine Offset stations. (added Cumulus 1.9.4 b1070) 0 = reporting off 1 = reporting on (default)

Other weather station/instrument specific:

Parameter Line Entry	Function
[Station]	Section name - the following parameters relate to the station configuration.
WMR928TempChannel=N	For WMR928 stations (and other stations using the same protocol, eg WMR968) to use an 'extra' channel as your main temperature sensor, set N to the required channel
WS2300Sync=1	This makes Cumulus check the time that the station is going to communicate with the sensors, and synchronises all of its reads to be 2.5 seconds after that. Experiments have shown that this does not help the bad data situation.
LCMaxWind=X	To use the cumulus.ini setting for the La Crosse max wind speed add to the [station] section, where X is the maximum (uncalibrated) wind speed in m/s that you want to allow. (V1.8.8 Build 874 on)
WS2300IgnoreStationClock=0	Option to ignore the La Crosse station clock on logger download. 0 = Disabled (default) 1 = Enabled
RG11port=1	Specifies the COM port to use for Hydreon RG-11 rain detection devices. 1 = COM1. Set on RG11 screen within configuration menu, see its Help for more information.
RG11TBRmode=1	Specifies the Hydreon RG-11 rain device mode of operation. 0 = Rain detection mode - "It's Raining" 1 = Tipping bucket mode. Set on RG11 screen within configuration menu.
RG11tipsize=0.01	Specifies the tipping bucket size for Hydreon RG-11 rain detection devices. The 'tip size' must be specified in the units that you have configured Cumulus to use for rain. Set on RG11 screen within configuration menu.
RG11port2= RG11TBRmode2= RG11tipsize2=	Settings to connect a second Hydreon RG-11 rain detection device. Set on RG11 screen within configuration menu. Note that you must have one RG-11 set to "It's raining" mode and the other to "tipping bucket" mode. Cumulus does not validate this.

Section: Offsets

Set these parameters using the Configuration menu and Calibration screen, nothing else can be added to this section.

Parameter Line Entry	Function
[Offsets]	Section Name - the following parameters are the correction factors for your specific sensors
PressOffset=0	Value by which Measured Pressure to be corrected (Add/Subtract)
TempOffset=0	Value by which Measured Outdoor Temperature to be corrected (Add/Subtract)

EnableRealtime=0	Set in the Internet Configuration screen Sites/Options tab Web Settings block. The realtime.txt file contains various weather parameters and is used by the CumulusRealtime.swf (shock wave flash) real time wind gauges (as on the supplied 'gauges' web page). 0 = Disabled (default) If you have the 'auto update' option set (and a suitable interval configured), Cumulus will create the realtime.txt file at the specified normal update Interval (not the Realtime Interval) so that you can specify it as an extra file to upload during the 'normal' upload, or use it for any other purpose on your PC. 1 = Enabled, Cumulus will create the realtime.txt file, and upload it to your web site, at the interval specified by Realtime Interval (see below).
RealtimeInterval=3000	Set in the Internet Configuration screen Sites/Options tab Web Settings block. The time in seconds between uploads of the realtime.txt file.
RealtimeFTPEnabled=0	Selected in the Internet Configuration screen Sites/Options tab Web Settings block 0 = Disabled (default) 1 = Enabled, Cumulus will establish an FTP connection to your web site, so that the realtime.txt file, and any other files you specify, can be uploaded when realtime processing takes place. The 'EnableRealtime' setting must be set to 1 for this setting to have any effect.

NOAAUseUTF8=0	(Added in Cumulus 1.9.4 beta build 1078) Specifies the 'Character set' in which NOAA reports are generated whether automatically (by Cumulus just after rollover) or manually (by selecting Save in NOAA Monthly/Annual Reports screen within Edit menu). 0 = Uses the encoding used for the viewer's operating system's default ANSI code page. 1 = Uses UTF8 ((UCS Transformation Format—8-bit) format - the dominant character encoding for the World-Wide Web as using one to three bytes it represents most characters in common use covering most languages.
NOAATempNorm[Jan-Dec]=	Long term temperature averages for each month, used for 'departure from the norm' calculations.
NOAARainNorm[Jan-Dec]=	Long term rainfall averages for each month, used for 'departure from the norm' calculations.
AutoFTP=0	If set, when Cumulus does the first FTP upload after the daily reset, it will also upload the latest auto-created monthly and yearly NOAA-style reports. Note that you must already have regular (non-realtime) FTP configured.
MonthFileFormat="NOAAMO"mmyy".txt"	Defines the format of the filename used for the monthly reports, using date formatting characters (see Webtags#Time.2FDate_.27format.27_Parameter). The default uses a 2 digit number for the month, but you may prefer the full month name or an abbreviation in your language. Note that any characters which are not date formatting characters should be in double quotes.
YearFileFormat="NOAAYR"yyyy".txt"	Defines the format of the filename used for the yearly reports, using date formatting characters (see Webtags#Time.2FDate_.27format.27_Parameter). Note that any characters which are not date formatting characters should be in double quotes.
FTPDirectory=	The FTP directory into which Cumulus will attempt to upload the latest NOAA-style reports. You must give the full path from the point of login, and do not supply a trailing 'slash'. Note that the directory must actually exist on the server.

Section: Solar

Set mostly in solar block at foot of Station Settings screen of Configuration menu.

Parameter Line Entry	Function
[Solar]	Section Name - the following parameters are set from the Solar Setup dialog in Cumulus
SunThreshold=75	If you have a solar sensor: Cumulus tries to determine whether the sun is shining by determining whether the current solar radiation value is above a certain percentage of the current theoretical maximum. The value you supply here is used as that percentage. The default value is 75%.
RStransfactor=0.8	Cumulus uses the Ryan-Stolzenbach formula to determine the current theoretical maximum solar radiation at your location at the current moment in time. This formula has a factor to allow for the transmission of the radiation through the atmosphere; the default is 0.80.
SolarMinimum=0	This setting allows you to specify a minimum solar radiation value which needs to be reached before it can be considered to be sunny. Note that this setting does not replace the calculation using the current theoretical maximum, it specifies an additional condition which has to be met. This setting therefore allows you to cater for the periods at the beginning and end of the day when the theoretical maximum is very low.
LuxToWM2=0.0079	Edit cumulus.ini to add this parameter if you have a Fine Offset station with a solar detector. These supply 'Lux' values rather than 'W/m2' values that Davis stations supply. Cumulus attempts to convert from Lux to W/m2 using the supplied multiplication factor.
UseBlakeLarsen=0	Called B/l on screen. Set this to 1 if you have a Blake-Larsen Sun Recorder, and you want Cumulus to get today's sunshine hours from it. You need to configure the Blake-Larsen software to put the SRsunshine.dat file into the Cumulus data folder so that Cumulus can read it.

Section: MainForm

This is an optional section if you have set 'Save main window position' on Display settings screen. This section appears in the main cumulus.ini (found in same directory as cumulus.exe) where it stores the position of the main Cumulus screen on your monitor. Cumulus updates this section of the main cumulus.ini on closing, after you move the screen around on your monitor. An equivalent section also appears in a shorter cumulus.ini stored in the reports sub-directory where it stores the position of your last saved NOAA screen.

Parameter Line Entry	Function
[MainForm]	Section name - the following parameters relate to the Cumulus screen position.
Left=100	The last saved Cumulus main screen position, in pixels from the left-hand edge of the screen.
Top=50	The last saved Cumulus main screen position, in pixels from the top edge of the screen
