基　　金：the National Natural Science Foundation of China(No.40633017 and 40575036);the National"973"Program of China(No.2006CB403700)The data were obtained from the NASA Langley Research Center Atmospheric Sciences Data Center.We appreciate Dr.Yuhong Yi for helping us with data and Mr.Jim Miller for smoothing the English;Funding for the processing of the northwestern China data was provided by the Special Professional Outlay for Scientific Research for Commonweal(No.GYHY(QX)2007);the Shanghai Leading Academic Discipline Project(No.B604)

摘　　要：The seasonal variability of cloud optical depth over northwestern China derived from Clouds and the Earth＇s Radiant Energy System （CERES） Single Scanner Footprint （SSF） Aqua Moderate Resolution Imaging Spectroradiometer （MODIS） Edition IB data from July 2002 to June 2004 is presented. The regions of interest are those with Asia monsoon influence, the Tianshan and Qilian Mountains, and the Taklimakan Desert. The results show that the instantaneous measurements presented here are much higher than the previous results derived from International Satellite Cloud Climatology Project （ISCCP） D2 monthly mean data. Generally the measurements of cloud optical depth are the highest in summer and the lowest in winter, however, Taklimakan Desert has the lowest measurements in autumn. The regional variation is quite significant over northwestern China.The seasonal variability of cloud optical depth over northwestern China derived from Clouds and the Earth＇s Radiant Energy System （CERES） Single Scanner Footprint （SSF） Aqua Moderate Resolution Imaging Spectroradiometer （MODIS） Edition IB data from July 2002 to June 2004 is presented.
