New data set release: SnowEx17 Radiometrics Surface-Based Radiometer Brightness Temperatures at NSIDC DAAC
The SnowEx17 Radiometrics Surface-Based Radiometer Brightness Temperatures, Version 1 data set is now available at the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC). This data set consists of surface-based radiometer (SBR) brightness temperatures of the snow surface and vegetation for 37 locations across Grand Mesa, CO. The data were collected during the NASA 2017 SnowEx campaign from 14 February 2017 through 18 February 2017. Four SBRs were deployed in the field and obtained measurements at 89, 37, 19, and 10.67 GHz in both vertical (V-pol) and horizontal (H-pol) polarizations. They include both 2 to 4-minute observations and 20-minute continuous measurements during surface melt, with the latter designed to capture the brightness temperature increase caused by the presence of liquid water in the snow. This data set also includes snowfork measurements of snow wetness for 13 of the 37 sites.
