内陆和沿海地区大气气溶胶标高的测量分析

Analysis on aerosol scale height measured at inland and coastal zone

在大气气溶胶粒子浓度随高度指数下降的假定下,气溶胶标高反映了大气边界层气溶胶的特征厚度。为了得到气溶胶标高随时空、季节和地域变化情况,根据整层大气光学厚度和近地面水平能见度的测量结果,分析了内地和沿海地区气溶胶标高的实际变化,初步得到了气溶胶标高随时间、地域及季节改变的规律。

Depending on the assumption that aerosol concentration index decreases with the altitude increasing, the aerosol scale height indicates boundary character thickness. In order to obtain the variable condition of aerosol scale height with the variety of time, season and zone, the actual variable of scale height was analyzed by using the measurement results of atmospheric optical depth and ground visibility at inland and coastal zone. At last the variable laws of aerosol scale height versus time and season were achieved.
