User notice: Updates to NASA AMSR-E/AMSR2 Unified data sets to cease on 01 September 2025

Updates to the NASA AMSR-E/AMSR2 Unified data sets, available at the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC), will cease on 01 September 2025. After this date, the NASA AMSR2 SIPS will stop processing and delivering updates to these datasets. If you currently utilize automated workflows to access new AMSR Unified data from NSIDC DAAC, please note these workflows will cease to function after this date. Additionally, no further reprocessing of existing AMSR Unified datasets can be expected. All AMSR Unified data archived at NSIDC DAAC prior to 01 September 2025 will remain accessible.

Level-1B, -1R, -2, and -3 AMSR2 data, and forthcoming AMSR3 data (scheduled for launch FY2025), will continue to be produced by the Japan Aerospace Exploration Agency (JAXA): https://www.eorc.jaxa.jp/AMSR/. For users who need continued access to new AMSR2 data, we encourage exploring access options through JAXA.

Access to the data and documentation for all AMSR Unified products archived at NSIDC DAAC can be found here: https://nsidc.org/data/amsru/data
