Satellite Observations of Arctic Change (SOAC)

Looking for the Satellite Observations of Arctic Change (SOAC)?

The NSIDC Satellite Observations of Arctic Change (SOAC) was an interactive website that transformed time series data from NASA satellites into interactive maps for users to visualize and study changes in the Arctic from 1980-2015. SOAC maps included surface air temperatures, sea ice extent and age, snow cover, frozen ground, atmospheric water vapor, and vegetation greenness. 

In May 2026, the SOAC tool was retired.
