New data set release: SMAP Ancillary Data

SMAP ancillary data sets are now available at the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC). These data sets are used to create SMAP Level-1, -2, -3, and -4 products and are made available as part of NSIDC DAAC’s mandate to preserve all SMAP data and related information for future research. Several of these ancillary data sets are produced by external organizations, such as NOAA, the NASA Global Modeling and Assimilation Office (GMAO), and NASA Land Data Assimilation Systems (LDAS).
