This SST layer is derived from infrared measurements collected by the MODerate Resolution Imaging Spectroradiometers aboard NASA's polar orbiting Terra and Aqua satellites. Energy levels at the top of the atmosphere in the 10-11 micron range (daytime) and 3-4 micron range (nighttime) are fit statistically to in-water SST measurements to allow 1km resolution SST estimates to be made. The resolution and accuracy of MODIS data are among the best available to Earth scientists today. These data are made available by the USF Institute for Marine Remote Sensing, http://imars.usf.edu.  DISPLAY NOTE : A land mask cover should be placed over this layer.
