The Community Snow Observations (CSO) project recruits community scientists to help collect snow depth observations -- anytime and anywhere, and submit via the mobile-sharing platform Snow Scope or desktop program Snow Pilot (SnowPilot.org). 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. Near real-time modeling results for many mountain domains across the United States are displayed daily on https://www.mountainsnow.org/.
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) Snow Scope app installed on your mobile phone (Android/iPhone)
3) Undisturbed snow
Have fun, and play safe in the snow!
