Robert H. Evans received his B.S. degree in 1966, his M.S. degree in 1970, and his Ph.D. degree in electrical engineering from North Carolina State University, Raleigh, in 1973. He has been a Research Professor at the Rosenstiel School of Marine and Atmospheric Science, University of Miami, Coral Gables, FL, since 1974. He was involved with the NIMBUS-7 Coastal Zone Color Scanner, developing an instrument calibration strategy and the processing methodology that provided the first global ocean color time series. He is currently a Science Team Member for SeaWiFS and MODIS investigations.

Research Area:
"Processing and Calibration for Ocean Observation with EOS/MODIS."

Provide an accurate characterization of the ocean related visible and infrared channels on the MODIS facility instrument. This activity is composed of three related parts: 1). utilization of MODIS measurements together with high-quality in-situ observations to provide a time history of calibration for each of the ocean bands (in-situ measurements provided by MODIS ocean team members, MOT); 2). integration of atmospheric correction algorithms of Gordon and MOT product algorithms with processing methodology developed at the RSMAS Remote Sensing Laboratory (RRSL) to provide products to support calibration and algorithm validation, and 3). provision of facilities necessary to support pre-launch radiative transfer modeling required by visible (Gordon) and infrared (Brown) studies and to compute post-launch calibration/validation fields. The breadth of challenges involved in computing meaningful oceanographic geophysical fields using satellite sensed visible and infrared fields is such that results from a number of contributing scientists need to be merged into a coherent processing and analysis path. Providing a framework for this integration is a key goal of this investigation.
