The SMAP Science Data System (SDS) has completed reprocessing of NASA SMAP Level-1, -2, and -3 radiometer data products to Version 2. The following data sets are now available for the full radiometer time series, 31 March 2015 to present, at the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC):
SMAP L1A Radiometer Time-Ordered Parsed Telemetry (SPL1AP) Data Set DOI: https://doi.org/10.5067/JGV8EY3FGAH1
SMAP L1B Radiometer Half-Orbit Time-Ordered Brightness Temperatures (SPL1BTB) Data Set DOI: https://doi.org/10.5067/VIQYQV0AJATI
SMAP L1C Radiometer Half-Orbit 36 km EASE-Grid Brightness Temperatures (SPL1CTB) Data Set DOI: https://doi.org/10.5067/Y9C3Q3060AZ5
SMAP L2 Radiometer Half-Orbit 36 km EASE-Grid Soil Moisture (SPL2SMP) Data Set DOI: https://doi.org/10.5067/3Q9102MCFF72
SMAP L3 Radiometer Global Daily 36 km EASE-Grid Soil Moisture (SPL3SMP) Data Set DOI: https://doi.org/10.5067/7EW92T1NI4M4
