Description:
Improved MODIS Dark Target Aerosol Optical Depth algorithm over land: Angular effect Correction Yerong Wu, Martin de Graaf, and Massimo Menenti Atmos. Meas. Tech. Discuss., doi:10.5194/amt-2016-185,2016 Manuscript under review for AMT (discussion: open, 0 comments) In this paper, we developed a new algorithm to improve the retrieval of Aerosol Optical Depth (AOD) over land with satellite measurement, by refining the shape of the spectral surface reflectance to improve the estimated background reflectance in the channel used for AOD retrieval. The results show that the angular effects of the retrievals are largely reduced, including fewer occurrences of negative retrievals. This implies that the users can get more accurate data without angular bias.
