== 8 March 2016 New S-NPP ATMS calibration == | |||
* On March 8, 2017 at 15:00 UTC NESDIS transitioned a new S-NPP/GCOM-W1 data processing/distribution systems to operations. This change incorporated updates to the ATMS calibration, resulting in a change in bias in the radiance measurements. Data processed with the new calibration apparently was included starting with the 12z March 8 ATMS file. | |||
* The GEOS-5 FP system responded immediately to the change by adjusting the mean term in the radiance bias corrections so there was no lasting effect in the observation statistics for bias-corrected channels. Channel 15 (not bias corrected) (O-F) flipped sign and was slightly improved. | |||
