Details/Specifics of Change:

On November 13, 2018 at approximately 13:37 UTC, the following update of the calibration coefficients was implemented in the level 1B processing for NOAA-18, NOAA-19, MetOp-A/2 and MetOp-B/1 for the month of November. These coefficients are intended to be optimal on November 27, in the middle of the two scheduled updates.
