photo of Changyong CaoChangyong Cao is a research physical scientist specializing in the calibration of radiometers onboard NOAA's operational environmental satellites. In addition to the operational pre&post calibration support, he is responsible for developing and refining the methodology for inter-satellite calibration using the Simultaneous Nadir Overpass (SNO) method, which has been used for the long-term on-orbit instrument performance monitoring of all radiometers on NOAA's polar orbiting satellites, and is being used by scientists for quantifying inter-satellite calibration biases in developing long-term time series for climate change detection studies. His primary research interest is climate quality calibration for earth observing satellites. He is co-chair of the Calibration Product Oversight Panel (CalPOP), and the chair for the GOES-R calibration working group. He also chaired the CEOS/WGCV (Committee on Earth Observation Satellites/Working Group on Calibration/Validation), the international committee for all space agencies from 2007-2008.

Before joining NOAA in 1999, Changyong was a senior scientist in remote sensing with the System Engineering and Technology Group at Lockheed Martin, NASA Stennis Space Center, where he supported a number of NASA projects, from hyperspectral spaceborne/airborne instrument preflight calibration, inflight radiometric and spectral calibration, validation and verification, to advanced remote sensing applications. He was an Assistant Professor and laboratory manager at Southern Illinois University in the early 1990s. Changyong received his Ph.D. degree in Geography specializing in remote sensing and geographic information systems from Louisiana State University in 1992. He received his Bachelor of Science degree in geography from Peking (Beijing) University in 1982.
