Satellite Observation-Based Study Reveals Historic Changes of PM2.5 over China and Trend Analysis

Based on trend analyses of anthropogenic and meteorological drivers, the average PM2.5 concentrations in polluted regions of China are expected to decline to 35 μg m-3 in 2021 in a scenario where emissions continue to decrease and meteorological factors are favorable. However, if emissions are held constant at current levels, meteorological drivers will lead to a rebound of PM2.5 concentrations in the future. These results strongly support continuous efforts for anthropogenic emission control to achieve a big decline of PM2.5 pollution in China.

Study Reveals Long-term Characteristics of Atmospheric Mixing Layer Height over Beijing

A research team led by Prof. LI Zhengqiang from the National Engineering Laboratory of Remote Sensing Satellite Application under the Aerospace Information Research Institute, Chinese Academy of Sciences, has made progress in pinpointing the characteristics of the atmospheric mixing layer height (MLH) over Beijing by laser radar (lidar). The paper titled "Determination and climatology of diurnal cycle of atmospheric mixing layer height over Beijing 2013-2018: Lidar measurements and implication for air pollution” was published online on July 27 in the journal of Atmospheric Chemistry and Physics.
