Abstract

In this paper, a theoretical study on the remote sounding of maritime atmospheric aerosols (MAA) from space is made. First, a simple transfer model of short wave radiation is established, then the criterion of channel selection for a general remote sounding equation is introduced. The channel for sounding an aerosol parameter is selected according to the degree of predominance (DP) of this parameter. After that, the DPs of various aerosol parameters are analyzed. The results show (1) it may be difficult to sound total aerosol number, aerosol size distribution parameters and aerosol complex refractive index simultaneously, (2) selecting channel in 0.60-1.10 micrometers is suitable for the space sounding of MAA's optical depth with the optimal position of channel in about 0.70-0.90 micrometers , (3) the two channels for the determination of MAA's Angstrom coefficient from MAA's optical depth should be selected in 0.65 +/- 0.1 micrometers and > 1.56 micrometers respectively, and (4) introducing more information about the reflectivity of ocean surface and the pressure of atmosphere at ocean surface etc. may be helpful to obtain more aerosol parameters.
