The AMSR-E/AMSR2 Unified L2B Global Swath Surface Precipitation, Version 1 data set is now available at the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC). This data set provides instantaneous surface precipitation rate and type over land and ocean, and precipitation profiles over ocean between 89.24 degrees north and south latitudes with spatial resolutions of 10 km spatial resolution along the track and 5 km spatial resolution along the scan. This product uses the Japan Aerospace Exploration Agency (JAXA) AMSR2 Level-1R input brightness temperatures that are calibrated (unified) across the JAXA AMSR-E and JAXA AMSR2 Level-1R products. The data set spans 02 July 2012 to present, but currently there are gaps in the temporal coverage which are in the process of being filled.
