摘要：

Long-term trend of surface solar radiation (SSR) in the Taklimakan Desert (TD) during 1980-2009 and its relationship to total cloud cover (TCC), low cloud cover (LCC), water vapor content (WVC) and aerosol optical depth (AOD) were investigated. Annual mean SSR has increased by 1.21 W m(-2) decade(-1). Upward SSR trends were observed in seasons except winter. TCC, LCC and WVC have increased, however, AOD and occurrences of severe dust storms have decreased, which indicates that dust aerosol rather than cloud cover and water vapor drive long-term upward trend of SSR in the TD.
