The SMOS-Based SMAP L2 Radiometer Half-Orbit 9 km EASE-Grid Soil Moisture and SMAP/SMOS L3 Radiometer 9 km EASE-Grid Soil Moisture, Version 2 datasets, available at the NASA National Snow and Ice Data Center Distributed Active Archive Center (NSIDC DAAC), have been updated through 9 October 2026. SMOS/SMAP L3 Radiometer 9 km EASE-Grid Soil Moisture (NSIDC-0800) data from14 May 2026 to 28 July 2026 have been reprocessed to correct for a geolocation issue discovered in August 2026. We recommend that users who previously downloaded NSIDC-0800 data from that time period redownload the corrected files.
