1 Remote Sensing at RSMAS – a new NESDIS connection Peter J. Minnett Meteorology and Physical Oceanography Rosenstiel School of Marine and Atmospheric Science University of Miami CIMAS Review February 20, 2003

2 Background Dr. Eric Bayler, Chief of Ocean Research and Applications at NESDIS intends to establish a new core funding line through CIMAS to support Ocean Remote Sensing at RSMAS. Activities to support NESDIS objectives. To complement new Cooperative Institute for Ocean Remote Sensing to be set up at Oregon State University. Anticipated initial funding ~$250,000 yr -1

3 Outline “Critical mass” at RSMAS in several aspects of ocean remote sensing. Examples of appropriate research topics: –Innovative optical-acoustic remote sensing in shallow water. –MODIS SST and chlorophyll-a developments. –SST validation. –SST application: hurricane prediction. –High resolution winds and waves from X-Band radar on Explorer of the Seas.

30 Ocean Upper Heat Content Reduction of heat content reduces energy available to support hurricane intensification. Use of low resolution, prior week interpolated data field does not adequately capture reduction of heat content, combined IR/MW SST provides more accurate assessment leading to improved hurricane forecast, using SHIPS. This research is in collaboration with the National Hurricane Center. Reynolds’ SST based heat contentCombined IR, µw SST based heat content From Nick Shay, RSMAS- MPO & Sean White, AOML
