Data Sources

Earth Observation satellite and Weather Model data is used to daily produce the underlying global snow dataset that powers both DeFROST Maps and API services. These sources include:

  • Sentinel-2, operated by the European Space Agency.

  • VIIRS onboard Suomi-NPP, operated by NASA.

  • MODIS onboard Terra & Aqua, operated by NASA.

Open Source Works

This section highlights some of the Open Source projects that make DeFROST possible and that we actively support.

Special mention goes to the Let-It-Snow module by CESBIO. DeFROST works with its custom extension of this module for the processing of Sentinel-2 scenes to detect snow on them.
