摘 要:An advanced along-track scanning radiometer(AATSR)global multi-year aerosol retrieval algorithm is *** land,the AATSR dual-view(ADV)algorithm utilizes the measured top of the atmosphere(TOA)reflectance in both the nadir and forward views to decouple the contributions of the atmosphere and the surface to retrieve aerosol *** ocean,the AATSR single-view(ASV)algorithm minimizes the discrepancy between the measured and modelled TOA reflectances in one of the views to retrieve the aerosol information using an ocean reflectance *** steps to process global,multiyear aerosol information are *** include cloud screening,the averaging of measured reflectance,and *** of the algorithms are also *** main product of the aerosol retrieval is the aerosol optical depth(AOD)at visible/near-infrared *** retrieved AOD is validated using data from the surface-based AERONET and maritime aerosol network(MAN)sun photometer networks as *** validation shows good agreement with the reference(r=0.85,RMSE=0.09 over land;r=0.83,RMSE=0.09 at coasts and r=0.96,RMSE=0.06 over open ocean).The results of the aerosol retrievals are presented for the full AATSR mission years 2002–2012 with seasonally averaged time series for selected regions.
