The Enhanced-Resolution SSM/I and AMSR-E Daily Polar Brightness Temperatures, Version 1 data set will be retired from the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC) on 31 October 2022. Access to the data will no longer be available, but the data set documentation will remain available for future reference. Alternatively, we recommend the MEaSUREs Calibrated Enhanced-Resolution Passive Microwave Daily EASE-Grid 2.0 Brightness Temperature ESDR data set, which contains enhanced-resolution, gridded passive microwave brightness temperatures, updated daily.
