| Abstract: |
| The method integrating ground-based Micro-Pulse Lidar (MPL) observation and WRF-Chem model simulation was used to analyze a severe haze incident in the central and eastern China from January 3 to January 5, 2015 to reveal the regional transport characteristics of aerosol PM in the haze. The lidar at the Xuzhou site detected particulate matters from 1-3 km away, respectively contributing 43% and 69% local pollution during the two inputs. The WRF-Chem model can effectively simulate the PM2.5 concentration, but the measured concentration tended to be higher than the estimation. Xuzhou was susceptible to haze caused by pollutants from western Shandong, eastern Henan, and northern Anhui, so the cooperation in these regions should be strengthened to achieve joint prevention and control. In recent years, the wind direction of winter in China was regular and the wind speed increased year by year, so the haze transport from North China to East China might become normal. |
