• NSIDC-0630 experienced a geolocation issue affecting the 6.9 GHz sensor channel files for AMSR2 before 1 January 2025 and for all AMSR-E dates. The geolocation offset is approximately 10 pixels (up to 250 km). The NSIDC DAAC is working to correct the issue and reprocess the impacted files in the coming weeks. Separately, AMSR2 forward processing is paused because the input data is not available. We are working with our data provider to determine a timeline for when the data will be available, at which point forward processing will resume.

  • AMSR2 satellite-based data products will continue forward processing for the foreseeable future. NSIDC is planning to develop AMSR3 data products in the future.

Overview

The Calibrated Enhanced-Resolution Passive Microwave Daily EASE-Grid 2.0 Brightness Temperature ESDR, Version 2 data set is a multi-sensor Level 3 Earth Science Data Record (ESDR) with improvements upon Version 1 in cross-sensor calibration and quality checking, modern file formats, better quality control, improved projection grids, and local time-of-day (LTOD) processing. These data are gridded to three EASE-Grid 2.0 projections (North Azimuthal, South Azimuthal, and Cylindrical) and include enhanced-resolution imagery, as well as coarse-resolution, averaged imagery. Inputs include brightness temperature data from the Scanning Multichannel Microwave Radiometer (SMMR), Special Sensor Microwave/Imager (SSM/I), Special Sensor Microwave Imager/Sounder (SSMIS), Advanced Microwave Scanning Radiometer - Earth Observing System (AMSR-E), and Advanced Microwave Scanning Radiometer 2 (AMSR2).
