Alaska Snow Survey Program


*** The Alaska Snow Survey Program webpage is in the process of a migration. Users may experience reduced functionality. Please contact us if you have any issues resulting from the migration


The NRCS Snow Survey Program provides mountain snowpack data and streamflow forecasts for the western United States and Alaska. Common applications of snow survey products include water supply management, flood control, climate modeling, recreation, and conservation planning.

Additional Snow Survey Information

Interim Issue Resolution: Air Temperature Data Bias

The extended range air temperature sensors used at SNOTEL sites in the continental U.S. calculate temperature from sensor output voltage using a linear least-squares regression algorithm. It has been determined that use of the linear least-squares regression algorithm has resulted in a data bias.

The Snow Survey and Water Supply Forecasting Program is actively working on a correction technique for this issue.
