Overview

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.

How to learn more about SMAP ancillary data

SMAP Ancillary data sets are used to produce SMAP Level-1, -2, -3, and -4 standard data products.

The following table describes both the required and actual latencies for the different SMAP radiometer data sets. Latency is defined as the time (# days, hh:mm:ss) from data acquisition to product generation.
