TRMM PR SIR-Enhanced EASE-Grid 2.0 Surface Radar Backscatter, Version 1

The TRMM PR product (NSIDC-0807), derived from the Tropical Rainfall Measuring Mission (TRMM) Precipitation Radar (PR) instrument, includes Level-3 gridded radar backscatter data collected at 13.88 GHz with vertical transmit–vertical receive (VV) polarization. Data are gridded to the EASE-Grid 2.0 cylindrical projections (Brodzik et al., 2012, Brodzik et al., 2014) at two griddings. Input data for the NSIDC-0807 product are the TRMM PR 2A21 Version-7 files obtained from the NASA EOS-DIS system. The data coverage is global for the period beginning in January 1998 through October 2014—the full mission lifetime. No calibration corrections have been applied to the data.
