BackgroundBackground

• 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

OutlineOutline• “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.

NESDIS - CIMASNESDIS - CIMAS• Candidate priority areas:

– Visible hyperspectral imagery in coastal areas– Atmospheric corrections for ocean color and SST– Validation of SST, for the climate record– Improved coastal forecasting using satellite data– Applications of ocean color data to fisheries– Assimilation of satellite data in ocean models– High resolution wind speeds from SAR and radar

scatterometry– Air-sea interaction in the tropical oceans, including

absorption of insolation in the water column

Examples of relevant Examples of relevant RSMAS researchS research

• Hyperspectral measurements in the coastal ocean

• SST from MODIS• Chlorophyll from MODIS• Accurate validation of SSTs• Improved coastal forecasting using satellite

data• High resolution winds and waves from X-Band
