Measuring Snow

Postby Charlie » Tue Oct 26, 2010 9:11 am

We are rapidly approaching the time when my rain guage turns into a block of ice for about 4 or 5 months, and it's a lot more interesting to measure snow fall. So, any ideas on how to do that?

I've toyed with the idea of something like a traditional rain guage - I can come up with a way to measure how high the snow is inside, but it would need to be emptied every day. And of course snow blows around, unlike rain that tends to stay in the same place once it's down... And it packs, melts and otherwise changes volume over time!

Maybe I should just go for total depth on the ground on an hourly basis, and let the value go up and down over the season. It would then be easy to calculate not only snow falls, but also the melt rate when spring comes.

Thoughts? Comments?

I'm planning to make up a heater for my rain gauge and melt any snow or ice but I don't think that would suit you. More suitable might be a graduated pole stuck in the ground - it could be marked in feet and inches or whatever units you use. You might want several as snow varies in depth as it's blown around. I can't think of any automatic way of measuring snow depth though there may well be such things.

Sorry, no banner - weather station out of action. Hoping to be up and running with a new home-made one soon.
