Remote sensing of the ocean from space Remote Sensing I Lecture 11 Summer 2006
Overview Sea surface temperature remote sensing Mapping of ocean colour –Biologic activity Remote sensing of sea surface height / topography from altimeters –El Nino detection –Deriving ocean circulation Remote sensing of sea surface roughness from scatterometers –Retrieving wind speed over the oceans
MODIS / Terra: Sea Surface Temperature Gulfstream
Ocean colour: MERIS/ENVISAT, 443 nm
