The SMAP Radiometer Twice-Daily rSIR-Enhanced EASE-Grid 2.0 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 contains twice-daily brightness temperature data derived from the SMAP radiometer and applies the same Scatterometer Image Reconstruction (SIR) technique used to derive brightness temperatures from the SMMR, AMSR-E, and SSM/I-SSMIS sensors. Data are available on the Northern Hemisphere, Southern Hemisphere, and Global EASE-Grid 2.0 projections, and on 3 km, 3.125 km, 9 km, 25 km, and 36 km resolution grids. This data set is available as part of an early release. Minimal documentation is currently available. An increased Level of Service and more detailed documentation will be available in the future.
