| 摘 要： | 根据１９９３￣１９９７年各年冬季清晨晴朗少云条件下所获得的ＮＯＡＡ－１２卫星云图资料，对西宁市区上空近地面大气层的污染物－－阴霾做了初步分析。首先总结了阴霾在ＮＯＡＡ－１２卫星云科上所呈现的物理量特征；其次利用这些特征计算了阴霾的面积、经纬度和中心经纬度值；最后从气象学方面证明了冬季西宁市区上空具有形成阴霾的条件。

Monitoring and Analysing Smog in the Ground Layer Atmosphere over Xining City during Winter with Remote Sensing Image |
| |
| Abstract: | Smog pollution in the ground layer atmosphere over Xining city,Qinghai province was analysed with the NOAA 12 remote sensing images obtained in cloudless dawns from 1993 to 1997. First,smog characteristics of the remote sensing images were studied. Second,the latitude and longitude of the smog area was calculated with these characteristics. Finally,the generation conditions of smog pollution over Xining city were given,and it suggested that the ground layer atmosphere over Xining city in winter is favourable to smog generation. |
