Contributions of meteorology and emission to the 2015 winter severe haze pollution episodes in Northern China
Abstract. Northern China in the 2015 winter months of November and December has witnessed the most severe air pollution phenomena since the 2013 winter haze events occurred, which triggered the first ever Red Alert in the air pollution control history of Beijing, with an instantaneous PM2.5 concentration over 1 mg m−3. Analysis and modeling results show that the worsening meteorology conditions are the main reason behind this unusual increase of air pollutant concentrations and the emission control measures taken during this period of time have contributed to mitigate the air pollution in the region. This work provides a scientific insight of the emission control measures vs. meteorology impacts for the period.

Short summary
Network monitoring data of air pollutants and meteorology as well as an air quality modeling system in the Beijing–Tianjin–Hebei region were used to analyze impacts the changes of meteorology on the variation of air pollutants. Results show that the worsening meteorology conditions are the main reason behind this unusual increase of air pollutant concentrations in the winter of 2015 and the emission control measures taken during this period of time have contributed to mitigate the air pollution.
