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.
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.

An update on the ORNL DAAC's Soil Moisture Visualizer (SMV) is featured in AGU's Eos, Earth & Space Science News.
Soil moisture estimates at the Walnut Gulch site, Arizona, reveal a dry soil surface, but considerably more moisture at 45 cm depth.
A new version of the AirMOSS root zone soil moisture data product is now available.

A new dataset provides an hourly, gridded soil moisture product for nine AirMOSS sites.
Estimated continental-scale Net Ecosystem Exchange (NEE) of CO2 in February 2012.
AirMOSS data provide daily estimates of Net Ecosystem Exchange (NEE) at seven Fluxnet sites, and hourly and monthly estimates for the whole North American region.
