Abstract: The imagers and sounders aboard NOAA's Geostationary Operational Environmental Satellites (GOES) provide quantitative data for weather forecasting and studies of the Earth's atmosphere and surface. This paper describes the post-launch radiometric testing of the imagers and sounders and present result from the instruments aboard the GOES-8, - 9, and -10 satellites. In these tests, we measure such quantities as nose and signal-to-noise ratios, radiometric responsivities and their variability, and detector 1/f noise. Performance anomalies specific to GOES, such as variation of scan-mirror reflectance with east-west scan angle, are characterized. The on-orbit results are compared with the performance specification, with pre-launch test result, and with results, and with results of post-launch tests of the imagers and sounders on other GOES satellites. !10
