Study and improvement on a retrieval algorithm of aerosol optical depth over ocean

By analysis on theories and methods of IMAPP's aerosol program, an algorithm to retrieve over-ocean aerosol optical depth using MOIDS data are provided. Its 1km resolution is better than IMAPP's, which makes it more useful in the study of regional climate change and regional air pollution than IMAPP. At the same time, this article validates that the observed spectral radiance of a single dot can be used to retrieve the aerosol optical depth over ocean with relatively high reliability, and that the aerosol distribution retrieved from MODIS data can offer basic data for the global or regional climatic change and air pollution research.
