摘要：

The remote determination Of surface temperature and surface spectral emittance by use of airborne or satellite-borne thermal infrared instruments is not straightforward. The radiance measured is a function Of surface temperature, the unknown surface spectral emittance, and absorption and emission in the intervening atmosphere. With a single measurement, the solution for temperature and spectral emittance is underdetermined. This article reviews two of the early approximate methods which have been fairly widely used to approach this problem.
