Topic: Scheduled Updates for MIRS

Date/Time Issued: September 29, 2020 1500 UTC

Product(s) or Data Impacted: MIRS products from POES, Metop, GPM and Megha-Tropiques

Date/Time of Initial Impact: October 29, 2020 1500 UTC

Impacts on Users and Significance: The v11r2 to v11r4 version update should be transparent to users. The users who are still pulling the MIRS Low-Res products need take action to switch to the MIRS high resolution products.

Details/Specifics of Change:

The following changes are scheduled on October 29, 2020

- Update the MIRS version from v11r2 to v11r4 for all legacy satellites, including N19, Metop-A/-B, GPM, to be consistent with that of S-NPP and N20. There will be no science changes during this update.

- Terminate the MIRS products from Megha-Tropiques

- Terminate the MIRS low resolution products
