Abstract :
The Multispectral Thermal Imager (MTI) is a satellite based push-broom imager that images in fifteen spectral bands from the visible into the long wavelength infrared. Five of its bands operate in the thermal infrared: J, 3.5-4.1 μm; K, 4.9-5.1 μm; L, 8.0-8.4 μm; M, 8.4-8.8 μm; and N, 10.2-10.7 μm. These bands allow the retrieval of water temperatures with a nominal ground sampling distance of 20 m. Several different algorithms have been developed to do retrievals with these bands. Comparisons with lake and ocean buoy data have been used to validate these algorithms.
