摘要：The official air quality statistic reported that Beijing had a 9.9% decline in the annual concentration of PM$_{2.5}$ in Year 2016. While this statistic offered some relief for the inhabitants of the capital, we present several analyzes based on Beijing`s PM$_{2.5}$ data of the past four years at 36 monitoring sites along with meteorological data of the past seven years. The analyzes reveal a mixed story regarding the air quality improvement in the fine particulate matter pollution in 2016, and provide more insights on the city`s PM$_{2.5}$ situation in the past four years.
