| 摘 要： | 基于HJ1A-CCD数据,采用6S大气辐射传输模型,反演出研究区气溶胶光学厚度。采用偏最小二乘法,基于气溶胶空间分布的估算结果,模拟出研究区PM_(2.5)的空间分布。基于GIS和改进的高斯大气扩散模型,进行了研究区PM_(2.5)的扩散模拟。根据我国PM_(2.5)检测网的空气质量新标准,对沈阳市的雾霾进行等级了划分。

| Abstract: | In this paper,the aerosol optical depth in study region was inverted from HJ1A-CCD data using 6S atmosphere radiation transmission model.The spatial distribution of PM2.5 in study region was simulated based on estimation results of aerosol spatial distribution,by adopting Partial Least Square Regression.The simulation diffused PM2.5 in study region was taken based on GIS and improved Gauss atmosphere diffuse model.According to the new standard of PM2.5 monitoring network in China,the smog level of Shenyang City was divided. |
