Topic: Interruption of ASCAT Soil Moisture Data Coming to SMOPS
Date/Time Issued: July 03, 2025 at 1825Z
Product(s) or Data Impacted: SMOPS data
Date/Time of Initial Impact: July 14, 2025
Date/Time of Expected End: TBD
Length of Impact: TBD
Details/Specifics:
The EUMETSAT Metop-B/C ASCAT Soil Moisture product is one input data of NESDIS Soil Moisture Operational Products System (SMOPS). EUMETSAT is working on replacing the ASCAT soil moisture file with a new version and stopping the old file on 7/14/2025. NESDIS is working on switching to the new ASCAT soil moisture data now. But it seems likely that there will be an interruption.
The lack of the Metop-B/C ASCAT soil moisture data will impact the accuracy of all SMOPS products as they will have data from 2 fewer satellites (out of the current 5).
