Abstract

Abstract

An operational algorithm of aerosol retrieval is described based on the FY-1C/1D data over global oceans.A sing le-channel algorithm is proposed.A look-up table(LUT) for aerosol retrieval is established using a state-of-art radiative transfer model 6S(second simulation of the satellite signal in the solar spectrum).The LUT shows that the apparent reflectance is the function of observation geometry (solar and viewing angles) and aerosol optical depth.Eventually,the LUT is used to retrieve the aerosol optical depth by the observed apparent reflectance.The data quality checking,cloud mask and sun-glint discrimination are considered during the operation processing.This algorithm has been used to test aerosol retrieval for FY-1C data since 2001 and introduced into the FY-1D operation performing including daily and monthly mean composite aerosol product since 2002.Analysis of the result reveals that all main aerosol sources are located over the global oceans and also reveals season variety in the globally averaged aerosol optical depth.They are nearly close to results of other similar foreign sensors in spatial distribution and numeral quantity.
