The ATOVS and IASI soundings products and the MiRS rain rate over the heavy precipitation areas are severely impacted by the anomaly. STAR scientists are working to find a substitute for AMSU-A channel 15 on Metop-B for these applications and they are making an assessment for a possible solution to the anomaly. Currently, no good retrievals are being made from the ATOVS and IASI using the Metop-B data. Users are recommended to use the available products with caution.
