【摘要】 本文利用太原市温室气体观测站(位于太原市观象台)的CE-318太阳光度计的观测资料,反演获得了太原地区AOD,同时计算了α,分析了该地区AOD和α的月、季变化特征,探讨了AOD和α的频率分布及其之间的关系。结果表明:太原市AOD月平均值3月和5月最高,其中5月为1.05,3月为1.03,11月最低为0.46。AOD在1-4月起伏波动较大,5-11月整体呈现下降趋势,12月又有所升高;太原市AOD的最大值出现在冬季,AOD的最小值出现在秋季;太原市AOD频率分布呈现出一定的单峰分布特征,较好的符合对数正态分布。与AOD的分布类似,太原市α频率分布也大致呈现双峰分布特征。更多还原

【Abstract】 The characteristic using the observational data of the CE-318 solar photometer in Taiyuan Xiaodian meteorological observation station, this paper retrieved the AOD in Taiyuan area and calculated alpha, analyzed the monthly and seasonal variations of AOD and alpha in the area, and discussed the frequency distribution of AOD and alpha and the relationship between them. The results showed that the average monthly AOD months in Taiyuan were the highest in March and May, which was 1.05 in May, 1.03 in March and 0.46 in November. The fluctuation of AOD in 1-4 months is larger, the overall decline trend in 5-11 months and the increase in December; the maximum value of AOD in Taiyuan appeared in winter, the minimum value of AOD appeared in autumn; the AOD frequency distribution in the city showed a certain single peak distribution characteristic, which was better in accordance with the lognormal distribution. Similar to the distribution of AOD, the alpha frequency distribution in Taiyuan also shows the characteristics of Shuangfeng distribution.更多还原
