SMAP L1B Radiometer Half-Orbit Radio Frequency Interference and Calibration Data V006
Listed in NASA Earthdata CMR
The SMAP L1B Radiometer Half-Orbit Radio Frequency Interference and Calibration Data (SPL1BTB_RFICAL) product is an intermediate Level 1B radiometer data product generated by NASA’s Soil Moisture Active Passive (SMAP) mission.
Description
SPL1BTB_RFICAL provides unaveraged, time-ordered antenna temperature measurements along with associated radio frequency interference (RFI) diagnostics, calibration parameters, and geolocation information.
Data are provided in half-orbit granules and represent radiometer measurements prior to RFI mitigation and spatial averaging. This product is intended for users performing instrument calibration assessment, RFI characterization, and algorithm development. It is not intended for direct geophysical analysis.
