Abstract

GOES-17 was launched on March 1, 2018, and became GOES-West at 137.2°W on February 12, 2019. The Advanced Baseline Imager (ABI) onboard GOES-17 has 16 bands to provide continuous data stream for weather forecasting and disaster monitoring. This poster summarizes the monitoring of GOES-17 calibration performance at the GOES-R Calibration Working Group (CWG), including radiometric, geometric, and spectral calibration. We monitor instrument calibration measurements and parameters, as well as the quality of the radiance product, including various accuracy and stability metrics of radiometric and geometric calibration. Our monitoring system has been an invaluable asset to users for instrument and products status, to instrument vendors for instrument anomaly diagnosis, to ground system vendors for software upgrade verification, to payload engineers for operational anomaly diagnosis, and to program managers for situational awareness. Several examples will be provided.
