摘要:The spatiotemporal variation of aerosol optical depth at 550 nm (AOD(550)), angstrom ngstrom exponent at 470-660 nm (AE(470-660)), water vapor content (WVC), and shortwave (SW) instantaneous aerosol direct radiative effects (IADRE) at the top-of-atmosphere (TOA) in clear skies obtained from the Moderate Resolution Imaging Spectroradiometer (MODIS) and Clouds and the Earth's Radiant Energy System (CERES) are quantitatively analyzed over the Yangtze River Basin (YRB) in China during 2001-2015. The annual and seasonal frequency distributions of AE(470-660) and AOD(550) reveal the dominance of fine aerosol particles over YRB. The regional average AOD(550) is 0.49 +/- 0.31, with high value in spring (0.58 +/- 0.35) and low value in winter (0.42 +/- 0.29). The higher AOD(550) (>= 0.6) is observed in midstream and downstream regions of YRB and Sichuan Basin due to local anthropogenic emissions and long-distance transport of dust particles, while lower AOD(550) (=-45 Wm(-2)). The correlation coefficient between the 15-year monthly IADRE and AOD(550) values is 0.63, which confirms the consistent spatiotemporal variation patterns over most of the YRB. However, a good agreement between IADRE and AOD is not observed in YRD and the source area of YRB, which is probably due to the combined effects of aerosol and surface properties.
