摘要: 利用中国科学院沙坡头沙漠试验研究站2001年9月至2002年5月的太阳光度计辐射资料,计算了该地区各月平均大气气溶胶光学厚度(AOT),并对该地区秋、冬、春三季平均的光学厚度进行了比较,同时对日变化也作了分析。此外,从反演的粒度谱分布也可以看出,春季该地区大气中的气溶胶粒子含量远大于冬、秋两季,并可以反映出春季大气层结的不稳定性,但反演方法的精度有限,还有待进一步提高。

Abstract: By using the solar photometric data of Tengger desert from Sep. 2001 to May 2002, we calculated the mean value of AOT of every month and compared these values with each other. Also we analyzed the diurnal variations of AOT. Moreover, from the size distributions inversed, we obtained that the content of aerosol particles in spring was the biggest. The size distributions also can reflect the instability of the atmosphere layers. But the accuracy of the method isnt high and we should study further.

Key words: Tengger desert, aerosol optical thickness, Junge size distribution
