| 摘 要： | 本文通过比较太阳直射表和太阳光度计探测的大气柱气溶胶光学厚度，分析了从太阳直射表探测的全波段太阳直射光强信息确定大气柱气溶胶光学厚度的误差，并应用北京观象台的太阳直射表观测资料，反演得到了 1990—1993年北京大气柱气溶胶光学厚度，分析了该光学厚度月与年变化规律以及1991年菲律宾皮纳图博火山爆发对北京大气气溶胶含量的影响。本文还提出了关于有效水汽含量的一个经验关系式，用于确定水汽对太阳辐射的吸收率。

| Abstract: | Based on a comparison of the columnar atmospheric aerosol optical depth measured by apyrheliometer and that a the sunphotometer, this paper analyzes the error in the optical depth dett rmined from the whole direct solar radiation detected by a pyrheliometer. According to 1990-1993 at tmospheric aerosol optical depth over Beijing area retrieved from solar radiation data measured by tilepyrheliometer at meteorological observing station in Beijing, the monthly and annual characteristics ofthe depth and the effect of the volcanic eruption of Mt. Pinatubo in 1991 on the atmospheric aerosolcontent in Belong are studied. Furthermore, this paper proposes an experimental formula of effectivH2O amount to determine the HZO absorptivity of the solar radiation. |
