The TRMM PR SIR-Enhanced EASE-Grid 2.0 Surface Radar Backscatter, Version 1 (NSIDC-0807), and ERS SIR-Enhanced EASE-Grid 2.0 Radar Backscatter, Version 1 (NSIDC-0808), are now available at the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC). NSIDC-0807 is derived from the Tropical Rainfall Measuring Mission (TRMM) Precipitation Radar (PR) instrument, which includes Level-3 gridded radar backscatter data collected at 13.88 GHz with vertical transmit–vertical receive (VV) polarization from January 1998 through October 2014. NSIDC-0808 provides normalized radar cross section or radar backscatter data derived from the European Space Agency (ESA) Earth Remote Sensing satellite series (ERS-1 and ERS-2) Active Microwave Instrument (AMI) in scatterometer-mode (ESCAT) during satellite overpasses between January 1992 and January 2001.
