摘　　要：采用2003年1月至2012年12月美国宇航局NASA发布的CERES SSF Aqua MODIS Edition 1B、2B和3A云资料,从冰水柱含量、云等效温度、云等效高度以及冰粒子等效直径4个云物理宏微观属性考察天山低层云水资源年际变化特征。结果表明:冰水柱含量均值在32.7~92.0 g/m2之间,云等效温度均值在214.9~257.3 K之间,云等效高度均值在3.9~5.7 km之间,冰粒子等效直径均值在12.7~22.4μm之间。冰水柱含量、云等效高度、云等效温度均呈降低的年际变化特征,冰粒子等效直径呈增加的年际变化特征。Using the data of CERES SSF Aqua MODIS Edition 1B/2B/3A from January 2003 to December 2012 and the data of the Clouds and the Earth's Radiant Energy System(CERES)of NASA's EOS, the inter-annual variation of lower layer cloud parameters, including ice water path, effective temperature, effective height and ice particle effective diameter, over the Tianshan Mountains was analyzed. The results showed that the values of ice water path, cloud effective temperature, cloud effective height and ice particle effective diameters of lower layer cloud over the Tianshan Mountains were in the range of 32.7-92.0 g/m2, 214.9-257.3 K, 3.9-5.7 km and 12.7-22.4 μm respectively. The cloud ice water path, cloud effective temperature,cloud effective height showed decreasing trends and ice particle effective diameter showed an increasing trend.
