Arctic Space Centre and Sodankylä Space Campus, Science News

The unique Sodankylä ground measurement network is utilized in the quality control of the global satellite-based monitoring of soil moisture and frost

Satellite applications are dependent on ground reference measurements to ensure the usefulness of the results.

Sodankylä region is particularly well suited for validation and comparison of various satellite measurements.
