Version 2 of the Calibrated Enhanced-Resolution Passive Microwave Daily EASE-Grid 2.0 Brightness Temperature ESDR data set is now available at the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC). This new version includes improvements in cross-sensor calibration and quality checking, modern file formats, better quality control, improved projection grids, and local time-of-day (LTOD) processing. It also involves changes in the data stream for SSM/I, SSMIS, AMSR-E, the addition of AMSR2 data, and changes to the filename structure. Version 2 currently includes data from January 2021 through March 2024. Back processing is ongoing to cover the entire time series, through October 1978. Version 1 will not be retired and will continue forward processing for the foreseeable future.
