THREDDS NetCDF Subsetting Service Bug Fixed

Unidata TDS

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.

A bug has been fixed in the THREDDS Data Server (TDS) NetCDF Subsetting Service (NCSS) that may, in rare cases, have returned incorrect results.

Tracking Permafrost with P-band SAR

AirMOSS Radar Swaths

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.

Airborne Microwave Observatory of Subcanopy and Subsurface (AirMOSS) radar data from Alaska are used to derive estimates of active layer thickness. Data from flights in 2014 and 2015 are now available.
