AMSU Retrieval Parameters, Metop 2: 0-12 Z

The IASI instrument on Metop-A (M2) ended operations early October 15, 2021. IASI data and products from Metop-A will no longer update. This is the first step in the planned retirement of the Metop-A satellite on November 15, 2021.

IASI products from other Metop satellites are unaffected.

Disclaimer
Currently, no good retrievals are being made from the ATOVS using the MetOp-A (MetOp-2) data due to the degradation of AMSU-A instrument data quality. However, the AMSU-A channel radiances (Brightness Temperatures) included in the ATOVS data file are not affected. The quality of the ATOVS Sounding products has decreased below specification. It is recommended that users should use the available sounding products with caution. We are investigating the problem and a decision will be made whether to terminate the affected ATOVS sounding products based on an upcoming assessment.

There are two time periods available for each group of data:
• Time period 1 covers from 00z to 12z of the current day.
• Time period 2 covers from 12z to 24z of the current day.

Note: There are 8 different retrieval parameters measured under AODF.
