Changyong 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.
