The NASA-funded Community Snow Observations (CSO) project recruits citizen scientists to help collect snow depth observations -- anytime and anywhere, and submit via the mobile-sharing platform Mountain Hub. The geotagged CSO observations are used to validate snow remote sensing products and to correct Snow Water Equivalence (SWE) measures in hydrological models for this region.
It is extremely easy and quick to participate! All you need is:
1) A measurement tool (an avalanche probe, or a yard stick will do!)
2) Mountain Hub app installed on your mobile phone (Android/iPhone)
3) Undisturbed snow
Have fun, and play safe in the snow!
