中文摘要	采用NASA地球观测系统(EOS)"云与地球辐射能量系统(CERES)"2002年7月至2004年6月CERES SSF A_(qua) MODIS Edition 1B云资料,对天山山区和塔克拉玛干沙漠云水资源进行了研究.得到的结果不仅包括云量、云液态水柱含量,还包括云滴尺度,为无人区的人工增水作业和天气气候研究提供了基础数据.与以往的卫星观测云气候全球数据集相比,该资料具有更高的空间分辨率,且其观测仪器和云反演方法得到了进一步改善,因此其结果较以往更可信.研究结果表明,两地区云参量年变化规律不尽相同,在数值上有很大差别.除了动力条件和气候背景以外,这可能与沙尘气溶胶可以影响云的物理特性和生命期有关.由年变化来看,天山山区的月平均总云量为47%72%,而塔克拉玛干沙漠为12%～50%;天山山区低云的月平均液态水柱含量为56.6～96.0 g/cm~2,高云为30.5～59.8 g/cm~2.而塔克拉玛干沙漠低云的月平均液态水柱含量为19.4～43.9 g/cm~2,高云为9.3～59.0g/cm~2;天山山区的月平均云滴半径低云为12.6～16.0 mum,高云为8.6～14.8mum克拉玛干沙漠地区低云云滴半径8.8～11.3 mum,高云为6.1～11.1mum.
英文摘要	Using July 2002 to June 2004 CERES SSF Aqua MODIS Edition IB data from Clouds and the Earth’s Radiant Energy System (CERES) of NASA’s EOS, cloud water resources over the Tianshan Mountains and Takli- makan Desert were studied. The results, which include not only cloud coverage, cloud liquid water path, but also cloud droplet size, were obtained in order to provide basic data for the operation of artificially enhanced precipitati- on and research of weather and climate at the uninhabited region. Compared with the previous satellite observations of global cloud climate datasets, the spatial resolution of the dataset used in this study is higher, and the observa- tional apparatus and cloud retrieval method has been further improved, so the results demonstrated here are more credible. The results show that the characteristics of annual variation in cloud parameters over the two regions are not always the same and the magnitudes are significantly different. Beside the different dynamic conditions and cli-mate backgrounds, the cause may be related to the fact that dust aerosols can affect the physical properties and life- time of the clouds over the Taklimakan Desert. The monthly mean of total cloud amount over the Tianshan Mountains was 47%～72% and that over Taklimakan Desert was 12%～50%. The monthly mean of liquid water path for low-level clouds over the Tianshan Mountains was 56.6～96.0 g/cm~2 and that over Taklimakan Desert was 19.4～43.9 g/cm~2 and that for high-level clouds over the Tianshan Mountains was 30.5～59.8 g/cm~2 and that over Taklimakan Desert was 9.3～mean of cloud liquid particle radius for low-level clouds over the Tianshan Mountains was 12.6～16.0 mum and that over Taklimakan Desert was 8. 8～ 11.3 mum and that for high-level clouds over the Tianshan Mountains was 8.6～14.8 mum and that over Taklimakan Desert was 6.1～11.1mum.
