AirMOSS

Sites in Version 2 of the Permafrost Dynamics Observatory Project product. Green = data delivered in Version 2. Red = not delivered in Version 2 but will be delivered in future version. Yellow = not processed due to only L-band data being available.

Unidata's THREDDS Data Server (TDS) is a web server that provides metadata and data access for scientific datasets, using a variety of remote data access protocols.

AirMOSS radar swaths flown in 2014 and 2015 in Alaska. In situ soil moisture and temperature profile measurements were obtained at the CALM (Circumpolar Active Layer Monitoring) and the UAF GIPL (Geophysical Institute Permafrost Laboratory, University of Alaska Fairbanks) sites and used to validate AirMOSS data products.
