For ''more information'' on these files see in the '''Cumulus help''' file, in the section “The Data log file”. This is installed with Cumulus 1, but can be read with Windows after downloading from [[Software#Resources]] page in this Wiki.
The table is split by Cumulus version for all changes since version 1.7.x (Steve Loft did not retain his list of changes in 1.4, his '''changes.txt''' is rather sparse in details for many releases, and the support forum excludes any posts before 2 Jun 2008, so earlier changes are not now documented).
#* MX since version 3.7.0 is more fussy, but less consistent, certain fields contain a single space when not used, others contain zero, and others can be left empty
#The final column describes the observation often with a link to where there is more information.
==Number of fields per line varies by release==
The fields that are available in the release you are running are listed in [[Monthlyfileheader.txt]] (found in folder level above the data sub-folder).
If you have some early files with fewer fields than the latest files, there are limited possibilities for calculating correct values for those missing fields
[[File:Badge v1.png]] For the legacy Cumulus software, the number of fields in the file increased as the software was developed. The Cumulus author, Steve Loft, did not provide any utility for populating fields missing from earlier versions of his software. A third party did produce a [[Calculate_Missing_Values#Using_a_PHP_script_on_your_web_server|PHP script]] that could:
* add Heat Index to lines created prior to 1.7.11
* add Apparent Temperature (not other fields, see below) to lines created before 1.9.1
* add Feels Like temperature (not other fields, see below) to lines created before 3.6.0
The fields that ''cannot'' be calculated by this script are (set them all to zero when editing file manually):
* UV Index
* Solar Radiation
* Evapotranspiration (spot value and annual cumulative total)
* Current theoretical max solar radiation
* Hours of sunshine so far today
* Current Wind bearing
* RG-11 rain today
* Total Rainfall since midnight (this is for 0900/1000 'rollover' users; normally same as rain today for 'midnight rollover' users)
[[File:Badge vMx.png]] As MX has developed, further fields have been added to the file at 3.6.0 and 3.6.12:
* Feels Like temperature
* Canadian Humidity Index (Humidex)
The main MX developer, Mark Crossley, has written a [[Calculate_Missing_Values#CreateMissing.exe|Create Missing utility]], this is dependent on having a significantly recent MX release, but it can calculate the following derived values (coping with cases where any of these are missing:
* [[Wind chill|Wind Chill]]
* [[Apparent_temperature|Australian Apparent Temperature]]
* [[Feels Like|Feels Like temperature]]
* [[Heat index|North American Heat Index]]
* [[Temperature_(and_humidity)_measurement#Dry_and_Wet_Bulb|Wet Bulb temperature]]
* [[Temperature_(and_humidity)_measurement#How_Cumulus_software_handles_Temperature_and_Humidity|Dew Point]]
* Rain since midnight
''Please note the developer does not mention any of this at [https://github.com/cumulusmx/CreateMissing/blob/master/README.md his utility details explanation] so the author of this Wiki update cannot guarantee the above list is correct''
You will need to check in MX release announcements for any update, at time of typing this, the developer has written a routine within CumulusMX.exe to calculate Evapotranspiration, but that is not in the CreateMissing.exe Utility.

''For Cumulus MX editing a file created by Cumulus 1'', any of the preceding fields that are not present will be '''defaulted to an empty string''', but there will always be 50 fields (unless you are using MX version before 3.6.0, it which case MX cannot read the file.
