For those people who use a 9 am or 10 am rollover, the '''yesterday.ini''' file will be updated twice each day, at midnight (when the [Solar] section is updated) and at rollover (when other sections are updated from today.ini, as the corresponding fields for the new [[dayfile.txt]] line are worked out). | For those people who use a 9 am or 10 am rollover, the '''yesterday.ini''' file will be updated twice each day, at midnight (when the [Solar] section is updated) and at rollover (when other sections are updated from today.ini, as the corresponding fields for the new [[dayfile.txt]] line are worked out). | ||

It may be noticed that '''yesterday.ini''' is (apart from solar exception to be described below) simply duplicating information shown in the existing latest line in [[dayfile.txt]]. Consequently, if there is a rogue value within "yesterday.ini", the correction should actually be made to the latest line found in [[Amending dayfile|dayfile.txt]]. | It may be noticed that '''yesterday.ini''' is (apart from solar exception to be described below) simply duplicating information shown in the existing latest line in [[dayfile.txt]].

Refer to the [[today.ini]] page for information on how Cumulus generates yesterday.ini from today.ini. | The files '''today.ini''' and '''yesterday.ini''' are used by Cumulus to store some counts, plus the Highs and Lows (and their timestamps) for key parameters as reached on each of the two days. | ||
Refer to the [[today.ini]] page for full information on how Cumulus generates yesterday.ini from today.ini. Here we just make a few comparisons: | |||
* See [[Average_temperature]] for one key transformation between '''today.ini''' and ''yesterday.ini''. | |||
* Please note, 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 from weather station is stored in '''today.ini''', but yesterday's total rainfall from [[Rain_measurement#Optical_Rain_Gauges|RG-11]] sensor is stored in ''yesterday.ini''. | |||
The original purpose of introducing '''yesterday.ini''' was simply to provide an easier way for Cumulus 1 to display yesterday's extremes on its main screen. The file is re-created at each rollover time, and Cumulus 1 would only read the file when Cumulus is restarted and the main screen needed to be generated. | The original purpose of introducing '''yesterday.ini''' was simply to provide an easier way for Cumulus 1 to display yesterday's extremes on its main screen.

However, ''when version 1.9.0 added '''Sunshine Hours''' as field 25'' in "dayfile.txt", a new use of "yesterday.ini" emerged. Sunshine hours are counted from one minute past midnight to the subsequent midnight. For those using a 9 am or 10 am rollover, the sunshine hours count will be reset to zero during their meteorological day, this means somewhere is needed to hold the previous sunshine hour count, thus the [Solar] section was added to "yesterday.ini" as it holds what goes into the new line of "dayfile.txt" when rollover happens 9 or 10 hours later. | However, ''when version 1.9.0 added '''Sunshine Hours''' as field 25'' in "dayfile.txt", a new use of "yesterday.ini" emerged.

You can view these figures, for Cumulus 1 these are source for figures that appear on the main screen, for Cumulus 2 and 3(MX) they appear in the admin interface pages you can view. These files are normally located in the "Data" sub-folder of the path where your Cumulus.exe is installed. See [[FAQ#I_can.E2.80.99t_find_my_data_files.21| FAQ on location of data log files]] for where else to look. | |||
