Heidinger's research at NOAA is focused primarily on cloud remote sensing using imagers. His projects included the development of new algorithms for operational satellites. In addition, he is involved with projects developing new remote sensing techniques and radiative transfer models for advanced satellite imagers. He is also interested in satellite calibration and analysis of long-term imager data sets. He has used techniques to exploit the information contained in visible to infrared frequencies to extract information on clouds, aerosols, and other atmospheric phenomena. This work is done in collaboration with other elements of NASA, NOAA, and academia.
