In addition to displaying model output from the CSO project, displays other sources of snow information. Read below to better understand what information is available for you to explore here.

Snow Data Assimilation System (SNODAS)

SNODAS models snow over the conterminous United States (plus a portion of Canada) on  a daily time step, but at a spatial resolution of 1 km. SNODAS assimilates in numerous sources of data, including Snow Telemetry (SNOTEL).


MODIS, or Moderate Resolution Imaging Spectroradiometer, is an instrument aboard the Terra and Aqua satellites. There are numerous products available from these missions. The MODIS product shown provides daily coverage at a 500 m spatial resolution. (As of 15 February 2023, these data are unavailable. We hope to restore this feature in the future).

Sentinel 2

The Copernicus Sentinel 2 mission provides revisit times on the order of 5 days and a spatial resolution of 10 - 50 m. Its imagery provides an unparalleled look at Earth's surface.
