Details/Specifics of Change:

On July 09, 2019 at approximately 12:29 UTC, the following update of the calibration coefficients was implemented in the level 1B processing for NOAA-18, NOAA-19, MetOp-A/2, MetOp-B/1, and MetOp-C/3 for the month of July. These coefficients are intended to be optimal on July 27, in the middle of the two scheduled updates.
