How to cater for snow in your records

[peterh]

No, Snowmageddon is not upon us, but... this morning as I came out, we had 4 cm of snow. When I get home, it'll probably be a wee bit more.

So... what is the accepted way to work this into your records? Do we measure the cm's snow and calculate it back to mms of rain (1 cm snow = 1 mm of rain) and correct the daily records?

Thinking about that, how do we deal, if at all, with hail?

[mcrossley]

It (snow/hail) just fills my rain gauge funnel, and I register as rain when it melts - which in Cheshire is usually pretty soon after it falls

Looks like we won't be so lucky this time.

Some people use a snow heater which then records the snowfall as rain; some cover up the rain gauge during the winter/snow season so don't record any precipitation during that time unless they record the snow manually; some - like me - just let the snow accumulate in the bucket (but much of it can't collect in it when we get many inches of snow), let it melt and record it when that occurs but this does distort the number of rain days, etc.

I also manually check/estimate the new snow fall in the previous 24 hours and the snow on the ground and enter that in the Cumulus Weather Diary, then also enter the new snowfall amount in the Cumulus console Current field so that both the new snow fall and snow on the ground is displayed in my http://www.komokaweather.com/weather/index.htm

Then there is also the official snow measurement, and CoCoRaHS http://www.cocorahs.org/ViewData/ListDa ... ports.aspx

This Console Current field - I assume that this is a feature of the 1.93 beta?

[PaulMy]

No, that has been there for a very long time. It is on the Cumulus console on your computer at the bottom. The text info you put in there becomes a webtag <#currcond> which you can then put anywhere for Cumulus to process at the usual web update interval.

Which, apparently, is disabled by default.
I just found it and enabled it. Thanks!

Note in Wiki http://wiki.sandaysoft.com/a/Cumulus.ini there is reference to 'SnowDepthHour=' as 'Snow lying/falling roll over time (time when yesterday's values in log.xml are forgotten) '

Also if you are able to program in anything that can draw for a webpage, the Cumulus web tag <#snowdepth> can be used to display a plot of the depth of snow, with similar code to that showing amount of rain can be displayed. Circumstances are such that I have not got access to my weather station at the moment, but I did have a plot that showed a green 'ground' minimicing grass with a vertical 'ruler' and javascript covered it with white according to the depth of snow.

Found it, enabled it and set it to 6am. Thx!
