IMPORTANT UPDATE: We are in the process of migrating this PO.DAAC website into Earthdata. Thank you for your patience as we make this transition. Read about the Web Unification Project.
SYSTEM ALERT: PO.DAAC will have a 48-hour data ingest and archive downtime. SWOT data will be affected on January 13, 2026 and Non-SWOT data will be affected on January 14, 2026. During this period, no data will be ingested, processed, or archived. We apologize for the inconvenience.
DATA ALERT: Temporary Issue with DSWx-S1 Data: Between May 20, 2025 and Nov 7, 2025, the Dynamic Surface Water eXtent from Sentinel-1 (DSWx-S1) product was affected by a processing issue that resulted in Sentinel-1A and Sentinel-1C data acquired on different dates occasionally being combined into a single product. After a software fix issued on Dec 9, 2025, all DSWx-S1 data going forward resumed normalcy. OPERA is in the process of replacing and reproducing impacted DSWx-S1 between May 20, 2025 and Dec 9, 2025 and expect to complete these tasks by Jan. 2026.
