Computer Models of 3-D Currents and TemperatureAlongtrack altimeter SSH data (dots) are used to “correct” themodel. GOES satellite SST is used to verify the improvement of themodel SST fields.prior (free-run) modelSSTmodel SST after SSHassimilationGOES daily SST (7/20/08),independent of model.48
Future Technologies“Next generation” satellite sensors are being developed by NASA and NOAA.• “Swath altimeters” will provide higher resolution SSH fields, closer to thecoast.• “Interferometer” scatterometers will provide higher resolution wind fields,closer to the coast.• “Hyper-spectral” ocean color sensors will sample the full visible radiationspectrum, allowing the identification of different types of phytoplankton,including those responsible for “harmful algal blooms” that close regions tothe harvest of shellfish. These will also have higher resolution to retrievedata farther up into rivers and estuaries.• SST sensors will combine the IR and Microwave channels to provide allweatherSST fields with higher resolution.• These satellite data and in-water data from subsurface “observatories” willbe “assimilated” into 3-D models of the ocean‟s circulation to providepredictions of currents, temperatures, oxygen (to warn of “dead zones”).Need more skilled people to analyze data from these systems!!
