| Abstract: |
| The paper aims to study the practical application of atmospheric gridding monitoring. The concentration of particulate matters in Jiading District, Shanghai from 2017 to 2018 was analyzed with the monitoring data of atmospheric gridding. The particulate matter pollution process was also analyzed with the data from scanning lidar. The results showed that the high concentration of particulate matter pollution was mainly concentrated in the northern region. PM10 and PM2.5 concentrations in 2017 ranked in the order of winter > spring > summer > autumn. The areas with high concentration of particulate matter pollution were occurred in the eastern and central parts of Jiading when the wind come from northeast by north. The large amount of exhaust gas emitted by enterprises at night can easily affect the air quality in the surrounding areas during the calm winds. The PM2.5 concentration from night to the next morning kept rising and was 3.1 times at 5:45 am than that of 20:00 pm the previous day. The environmental quality of Jiading District is improved obviously by the implementation of atmospheric gridding monitoring and the regulation of atmospheric emission reduction. |
