摘要
利用地面遥感O_3垂直分布的逆转方法〈C〉测量出的北京上空O_3剖面资料,对雨云7号卫星的SBUV系统测量的同地区的O_3垂直分布数据进行了订正.对订正后的长达8年(1979—1986年)的完整的SBUV资料进行了较为仔细的分析,得出了这一时期内的O_3垂直分布长期演变呈下降趋势.并在上层O_3含量的季节变化特征和周期振荡等方面,有新的发现,得出一些有意义的结果.
The SBUV ozone vertical profile data over Beijing from the satellite Nimbus 7 have been compared and corrected with our ground remote sensing data by the Umkehr method (C). Then, the complete SBUV data during the period Apr. 1979-Oct. 1986 have been analysed in more detail. Some new and interesting results have been obtained.1.The trend of the upper level (above 28 km) ozone over Beijing area was a little bit larger than that of the lower level (below 28 km); their values were about -7% to-8% and about - 5% respectively during the period of 1979-1986. These include the influences of solar cycle and Q. B. ,O. etc.2.A more complete pattern of seasonal variations of the ozone vertical profile is presented. It shows complete opposite phases between the layer of 28 - 36 km and the layer of above 36 km.3.The oscillations with the period of quasi-27 days and quasi-10 days of the ozone amount above 36 km have been found in the Winter-half-year.
