Today.ini

Introduction

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 normally located in the Data sub-folder of the path where your Cumulus.exe is installed. See FAQ on location of data log files for where else to look.

The highs and lows are held in memory while Cumulus is running. At the end of a day [either midnight, or 9am (or 10am) depending on your configuration and season], the final values and timestamps written to today.ini file are rolled-over to become values and timestamps in 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 restart Cumulus during the day it will read both these files at startup, so it can resume tracking extremes of the key parameters starting from latest stored values in today.ini. Equally, if you close Cumulus during the day it will write the final values for highs and lows and their timestamps to today.ini as part of the close down process.

Dealing with rogue values

The today file is written to throughout the current day as any new High or Low for the day at reached. If your weather station reports a rogue value, an incorrect update to the High or Low may result, but details of that update should be in the Diags, so look there to see what correction will be required to eliminate the rogue value. Normally you would not need to edit today.ini, as if you wait until the next day, Cumulus provides (with its Edit menu) an easy way to amend the stored extremes for this month, this year, monthly records, and all-time. The wrong figures may be displayed on the yesterday screen for this next day, but yesterday.ini can be edited more easily!

Note: If you do decide to edit today.ini outside Cumulus, you must close Cumulus down first!

Editing today.ini within Cumulus

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 (or indeed under-reported). The stored rainfall today value in today.ini may be edited within Cumulus via Today's rain screen on the Edit menu. This edit does not affect any false derived rainfall values for the month or year, unless you subsequently close and restart Cumulus the same day to force recalculation of the longer period totals.

Editing today.ini or yesterday.ini outside Cumulus

If the rogue value is not rainfall, then you might need to edit today.ini or yesterday.ini using an external editor. Note: If you do edit either of these files, you must close Cumulus down first!

The files are text files, so edit using any plain text editor. The format consists of a number of sections (section title is delimited by []), and a number of properties (consisting of attrbute name, an equals sign and a value). Blank lines can be included for readability, they are ignored in these .ini type log files. All values have to be specified in the correct format, see example below.

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 from weather station is stored in today.ini, but yesterday's total rainfall from RG-11 sensor is stored in yesterday.ini.
