Topic: Jason-3 product outage

Date Issued: April 25, 2021 1230Z

Product(s) or Data Impacted: Jason-3 Operational Geophysical Data Records (OGDRs)

Date/Time of Initial Impact: April 24, 2021 15:33:15 UTC

Date/Time of Expected End: April 25, 2021 01:19:23 UTC

Length of Event: 9 hrs 46 min 8 sec

Details/Specifics of Change:

Due to an AMR (advanced microwave radiometer) anomaly on the Jason-3 satellite no AMR data was available from 15:33:15 UTC on April 24, 2021 until 01:19:23 UTC  on April 25, 2021.

As a result, sea surface height data was not computed for the following associated OGDRs (Operational Geophysical Data Records):

Ocean models dependent on sea surface height measurements will be affected. Significant wave height and wind speed were not impacted.
The AMR is used to measure the wet troposphere, to provide a correction to the sea surface height measurement.
