Final Cumulus 1 version

Cumulus 1 has now been described as Legacy Software, simply because it is no longer supported, and can no longer be updated.

If you want to run Cumulus 1.9.4, there is no reason why you should not. It is a stable release, and only one bug has been identified.

The single known bug is that the original Cumulus software uses the wrong memory location for pressure for Fine Offset models. These weather stations are also considered legacy ones. There is a workaround described at FAQ#Cumulus_doesn.E2.80.99t_show_the_same_pressure_as_my_Fine_Offset_console.

Download Instructions

Please refer to Setup page first, so you understand how the installation process works. A more detailed (but now out of date) guide can be downloaded from Cumulus basic installation guide.pdf.

This is a multi-stage process:

1. First Download the Windows Installer Package, the CumulusSetup.exe file here.
   • (There are two special alternatives, their download links appear later on this page)
2. Choose a location where you will install the software on your Microsoft Windows device
   • It is best to install to a root of whatever drive has plenty of spare space, this might be where you are using for your working files or normal documents
3. Now run the installer, so it creates a large number of files and folders, (make sure the files and folders are installed in right location)
   • As you run the installer, read the instructions it displays . This read me text can also be downloaded from a link in the resources section below
4. When the installer has completed, there is another download to do.
5. Now download the patch available here.
6. Take the file "Cumulus.exe" from the patch, and use it to replace the file "Cumulus.exe" from whichever of the three installer packages you used earlier
7. All other files from the full release, must be retained after applying the patch. The patch does not change any of the compiled code, nor its functionality.
8. Start running Cumulus as instructed on Setup page.

Additional guidance

Date Selection

• You can type any year you like into selection boxes on view month, view year, view period, and view NOAA report.
• As well as directly typing in a date including a year into the selection box, you can pick a a date from the drop down boxes that can select year, and (where relevant) month and day.
• The windows installer version of the year drop-down selection only contains years 2008 to 2020.
• The patch changes the year drop-down selection to contains the years 2020 to 2030, making it easier for the current decade (at time of typing this) as it allows you to select years up to 2030 from a drop down in the relevant screen box.

Cumulus Help

One of the attractions of the original Cumulus software is that the installer installs a detailed set of help screens, so that each screen has a button that you can click for assistance, and the Main Screen has a Help menu where you can look up more guidance, such as web tags. The 1.9.4 helpfile can also be downloaded (for viewing using Windows Help) from link in resources section below. At the time of typing, it can also be viewed at Cumulus Top Weather Sites. See below for a translation into French.

Earlier Versions

Steve Loft, as well as updating the support forum with announcements about his releases for Cumulus 1, maintained an abbreviated summary in changes.txt, find it at File:Changes.zip. It covers releases back to version 1.0, the first release on 27 January 2004, although the documentation for a small range within that was lost.

For the way dayfile.txt changed between versions, see that link.

Special Cumulus 1 versions

If you are an Instromet user, and your logger operates at 115200 baud, you should use special build 1100 at special 1.9.4 build 1100.

If you are an Instromet user, and your logger operates at 19200 baud, you should use special build 1101 at special 1.9.4 build 1101.

The patch, available in download above, can be applied after installing either of these special versions, it changes the GUI to make the drop down list cover years 2020 to 2030. As mentioned above, the patch only replaces the .exe file, all other files from special versions are retained.

Note about this article

When Steve Loft was about to retire from involvement with Cumulus, he wanted to close his web server. His server (sandaysoft.com) had hosted the wiki, the support forum, and some of the downloads were at http://sandaysoft.com/downloads. The other downloads (used mostly for beta and special releases) were at http://www.nybbles.co.uk/downloads which was also closed.

In October 2018, Ken True ("saratogaWX") offered to host the Wiki on his site. The Cumulus 1 software files were downloaded from the links mentioned above, and then added to this "Downloads" page by Ken as part of the migration of the Wiki.

The next month (November 2018), Steve Loft sought a new host for the support forum, as next part of closing his web server. The Cumulus MX beta that Steve Loft was writing and hosting on his web server was available as a download within the support forum. When Niall Hosiene ("Freddie") took over hosting of the forum, all the forum contents, including attached files, were moved to his server.

It appears (as the main page suggests "We've added download links for Cumulus V1 and Cumulus MX in the new Software/Downloads page ") there was a bit of conflict between Downloads page and Software page.

• Ken True created new "Downloads" section in this Wiki referenced from other pages; to this were added the Cumulus 1 final version software download, the help file download and the Cumulus 1 special downloads for Instromet.
• Mark Crossley on taking over Cumulus MX development created a new Wiki page just for links to his GitHub pages where the source and distributions for MX are now held (instead of as attachments to forum posts).
• Niall Hosiene edited the new Software page to make it one destination for both MX and Cumulus 1 software, he overlooked that other pages in this Wiki were linking to the original Downloads page. He was so keen to promote MX, his edit downgraded Cumulus 1 to legacy and the links to the various Cumulus 1 downloads were consequently made harder to spot.

Subsequently:

1. this wiki page has been resurrected for Cumulus 1
2. the Software page has been improved by Ken True, and now has better links to Cumulus 1 and the patch.
