About Us

What we're doing

This project aims to improve our understanding of snow depth variability in mountainous regions. We need community-based observers, including backcountry professionals and recreationists, to help gather snow observations.

Uses of snow data

"On the ground" measurements aid interpretations of satellite and airborne snow measurements collected by NASA and other agencies.

Snow data help improve water runoff models. Predicting and understanding variability in water runoff is important due to effects on snow avalanche hazards, water resources, ecology, tourism, and the impacts of a changing climate.

Citizen scientists will learn more about snow depth distribution. This can help them them make better decisions while navigating in avalanche terrain.

Map of observations made all over the United States using the Mountain Hub app.

Partners and funding

Alaska Climate Adaptation Science Center  •  International Arctic Research Center  •  Mountain Hub  •  Oregon State University  •  Snow Pilot  •  State of Alaska Division of Geological & Geophysical Surveys  •  University of Alaska Fairbanks  •  University of Washington

We are funded by NASA’s Earth Science Program, as part of the NASA Citizen Science for Earth Systems project.

Science team

We are a group of scientists at United States federal, state and university agencies who are fascinated by snow in all its various forms. We participate in citizen-science just like you, except our day jobs are also science!
