The Weather Diary feature allows the user to enter some short notes (up to 1024 characters) for each day, and to record whether snow was falling and/or lying on that day, along with the depth of snow.
If you have manual weather observations, or want a permanent record of general conditions each day, this diary is the place to hold such notes.
Anybody with experience of using this feature is encouraged to contribute to this article.
How to find this feature
On the main Cumulus screen select Weather Diary from the View menu.
How do I change the time a diary day begins/ends?
The diary loads displaying the current calendar day.
This may not be the right day to enter current information as the rollover time for Weather Diary information is configuable using Cumulus.ini e.g. SnowDepthHour=9 means everything (not just snow depth) in yesterday's diary entry applies until 9am. The SnowDepthHour label applies because the only part of the diary that is converted to a Webtag is Snow Depth, and the time set is when <#snowdepth> is updated with the current day's value, until then it shows the value on yesterday's diary page.
NOTE: This rollover time is totally independent of any overall 'log rollover' time set in station screen as accessed from Configuation menu. You may use midnight rollover, but want to go out and record manual observations (including measuring any snow) each morning at 9am (or any other time).
Where is the information stored?
See Log.xml This file can be opened as a text file, but there are database file readers that can open this sort of file and display them in a spreadsheet like format (or even convert them to formats like CSV). It is possible to upload this file, or a transformed version of it, onto your webspace and write coding to display the contents.
The weather station models that Cumulus is programmed for do not include any automated snow measurement. So Cumulus does not treat Snow the same way as automated measurements (until it melts and any left on top of, or inside, a rain gauge is counted as rain). Instead Cumulus assumes you will manually insert information.
Entering Snow Information
You can go outside with a ruler and measure the depth of any lying snow. The option Weather Diary within the View menu allows you to navigate to the appropriate day (see above) and:
- make a text note (this might cover include the time snow started falling, and/or stopped falling or something about the intensity of the snow storm),
- tick snow lying (this is a snapshot, you can only tick/untick for the whole day),
- enter an integer representing the snow depth at your chosen updating time (this can be in any units, mm, cm, inches, thumbnails or marked stick - just remember to always use the same units as the units are not recorded)
- tick snow falling (this is a snapshot, you can only tick/untick for the whole day).
Click update button, or all your entries will be lost.
Displaying on a customised web page
Some sites use the current conditions feature (optional box on main screen, plus ability to create a file that is deleted on use - see Cumulus help) to display further snow information.
Some sites using Cumulus and updating databases as input for creating pages using PHP do manage to display other information from the diary on their web sites (search the support forum for mentions of snow).
