The AMSR-E/AMSR2 Unified L3 Daily 6.25 km Polar Gridded 89 GHz Brightness Temperatures, Version 1 data set is now available at the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC). 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 AMSR2 Level-1R products. Data are mapped to a polar stereographic grid at 6.25 km spatial resolution and are available from 2 July 2012 through the present.
