Topic:  GOES-18 software build/patch (PR.12.02.00) implementation

Date/Time Issued: May 3, 2023 1854 UTC

Product(s) or Data Impacted: GOES-18 ABI L2+ products

Date/Time of Initial Impact: May 18, 2023 

Date/Time of Expected End: N/A

Length of Outage: N/A

Details/Specifics of Change: On May 18, 2023, the PR.12.02.00 software patch will update the Fast Planck tables used by the GOES-18 ABI L2 algorithms. Previously, all GOES-R satellites were using values that were calculated for GOES-16. This update will result in a minor improvement to many of the derived L2 products for GOES-18 (i.e. no change to imagery); but most notably, it will resolve the misclassification of water clouds as ice clouds that occurs near the edges of some clouds in the GOES-18 Enterprise Cloud Phase product. 

There will be no change to the tables for GOES-16, and therefore no change to the quality of the GOES-16 ABI L2 products.
