Data Set ID: 
SPL1BTB

SMAP L1B Radiometer Half-Orbit Time-Ordered Brightness Temperatures, Version 2

This Level-1B (L1B) product provides calibrated estimates of time-ordered geolocated brightness temperatures measured by the Soil Moisture Active Passive (SMAP) passive microwave radiometer. Brightness temperatures are referenced to the Earth's surface with undesired and erroneous radiometric sources removed. Sources of contamination include Faraday rotation, energy detected from antenna sidelobes and spillover, atmospheric effects, solar radiation, lunar radiation, cosmic microwave background, and galactic emission.

There is a more recent version of these data.
