- Abstract
Numerical experiments on the simultaneous retrieval of the temperature and spectral emissivity of different land types are performed on the basis of inversion of the simulated high spectral resolution measurements by the IRFS-2 satellite IR sounder. The IRFS-2 data inversion method is based on using a priori information on the spectral behavior of emissivity of different land types and the multiple linear regression technique. The rms errors of determination of the underlying surface temperature using different solving operators are 0.26-0.71 K. The application of the developed IRFS-2 measurement inversion method makes it possible to estimate the land surface emissivity with an rms error not larger than 0.015.
