Storm Clouds Posted January 12, 2011 Share Posted January 12, 2011 I do not know how to do it. Last night it snowed and today the snow melted in my rain gauge (Davis VP2 station) and read .03. How do I convert .03 into inches of snow? Thanks. Link to comment Share on other sites More sharing options...
jasonli18t Posted January 12, 2011 Share Posted January 12, 2011 umm lol you dont. you measure snow when it exists. you don't reverse measure snow. this is like a twilight zone post. Link to comment Share on other sites More sharing options...
Scotty Lightning Posted January 12, 2011 Share Posted January 12, 2011 First you need to find out what the temp was when the precip fell. Then you can use http://www.erh.noaa....-mel****er.html (that word in there should be "melt water") Link to comment Share on other sites More sharing options...

Scotty Lightning Posted January 12, 2011 Share Posted January 12, 2011 Okay thanks...but the link is not working. You have to write in the "melt water" part in(without spaces). The word filter noticed the "t w a t" part in the word and it censored it. Link to comment Share on other sites More sharing options...

Then you can use http://www.erh.noaa....-mel****er.html (that word in there should be "melt water") Don't use that table. You can't do that kind of conversion... snowfall-to-liquid ratios are based on dynamics and temps above the surface, not on temperature at the surface (unless that temperature at the surface is above freezing). You need to go buy a manual rain gauge to get the real snow water equivalent, like a CoCoRaHS gauge. http://www.weatheryourway.com/cocorahs/store.html Automated gauges don't do very well in snow, heated or not. A manual measurement made by melting the snow is always the best way to figure out the water content. As far as measuring the snow, follow the instructions here: FYI, 0.03" of liquid would translate to anywhere between 0.3 and 0.6 inches of snow, generally speaking.

Thanks much! Yeah, I definitely do not have 0.3-0.6 on the ground right now! I have more like 4 inches! So, I guess my Davis VP2 rain gauge is inaccurate with snowfall! Manual measurement is the way to go right? Link to comment Share on other sites More sharing options...
