Relevant equations used in Remote Sensing Stefan-Boltzmann’s law M = omegaT4 where omegaM = total radiant exitance from surface (W/m2) omega = Stefan-Boltzmann constant = 5.6697 x 10-8 Wm-2K-4 T = absolute temperature (K) of the surface The law is expressed for a blackbody Wien's displacement law max wavelength = 2897 µm x °K(constant) divided by radiant Temperature This law calculates the wavelength of maximum emittance for a given temperature. Plank's law Source: http://cimiss.ssec.wisc.edu/goes/comet_new/4.html Plank's Law determines the emission spectra or pattern of eletromagnetic radiation of a black body as a function of temperature and wavelength.
