photo of Changyong CaoChangyong Cao oversees the satellite instrument calibration and data assimilation branch which is responsible for the instrument performance and data quality for all operational polar-orbiting and geostationary satellites at NOAA. He leads the STAR radiance science team, Visible Infrared Imaging Radiometer Suite (VIIRS) instrument calibration/validation team, and co-lead the GOES Advanced Baseline Imager (ABI) calibration working group (CWG). He developed the Simultaneous Nadir Overpass (SNO) intersatellite calibration method, which has become one of the cornerstones of the WMO/Global Space-based Intercalibration System (GSICS), widely used for on-orbit instrument performance evaluation for Earth observation satellites, and for long-term time series and climate change detection studies.

Dr. Cao has broad research interests in satellite instrument performance characterization, exploration of novel uses of satellite observations and new technologies. He is advisor to the WMO/GSICS, and former chair of the CEOS/WGCV (Committee on Earth Observation Satellites/Working Group on Calibration/Validation). He is the recipient of three gold and one silver medals from the Department of Commerce and NOAA for his achievements. Before joining NOAA, Changyong was a senior remote sensing scientist with a leading aerospace company supporting NASA missions.
