Today.ini
The files today.ini and yesterday.ini are used by Cumulus to store the Highs and Lows (and their timestamps) for key parameters as reached on each of the two days. These files are located in the Data sub-folder of the path where your Cumulus.exe is installed.
The today file is written to throughout the current day as any new High or Low for the day at reached. At the end of a day [either midnight, or 9am (or 10am) depending on your configuration and season], the today.ini file is rolled-over to become yesterday.ini and a new today.ini is created. From the examples below you can see that the two files have a few differences in content, so rolling-over does involve a little editing work.
If you close down and restart Cumulus during the day it will read these files at startup, so it can resume tracking extremes of the key parameters.
Normally you would not need to edit these files, however rarely you may wish to edit the rain data if there has been a quirk in your weather station reporting during the day and the figure is abnormally inflated. Note: If you do edit either of these files, you must close Cumulus down first!

Example yesterday.ini
See Average_temperature for one key transformation between today.ini and yesterday.ini, no ET parameters are retained, plus there are some wind and some rain parameters not copied from today.ini to yesterday.ini.
NOTE: Yesterday's total rainfall is stored in today.ini, but yesterday's RG11 rainfall is stored in yesterday.ini.
