Abstract

Three models of land surface polarized reflectance are evaluated using data obtained from newly developed advanced atmosphere multi-angle polarization radiometer (AMPR) and laboratory. The spectral and angular responses are analyzed. It is found that the spectral response is very little, and 85% of AMPR aerosol retrievals support the result. For the data from laboratory, the changes of polarized reflectance of yellow brown soil and red sandy soil are just 2.43×10-6 and 1.47×10-6 as the wavelength changes 1 nm. Angular responses of all three models match the measured data well with less difference between the high vegetation coverage data and models. After fitted, the model developed by Nadal and Bréon (NB) agrees with the measurements best, and the difference is about 1/2 of the other two models. NB model can describe the surface polarization more exactly.
