AVHRR Bandwidth Tutorial

The previous page dealt with the wavelength range of AVHRR satellites, but how are these bandwidths manipulated into quantifiable data? The following pictures are the products band ratios yield:



Channel 1: AVHRR MCSST, or Multi-Channel Sea Surface Temperature. SST is derived using two algorithms, IMGMAP and OCNMAP, which use the difference of Infrared channels 4 and 5 as a parameter.
