Chongqing Air Quality Characteristics and Relationship with Meteorological Elements

Abstract:

Analyze the air pollution index (API) variation characteristics in Chongqing, and the relationship between API and meteorological elements. Found that air quality of Chongqing is basically at level II. Primary pollutant is inhalable particle (PM10). Summer is the season with best air quality, while winter is the most polluted season. Visibility, precipitation, sunshine and other meteorological elements have a great effect on the variation of air quality. The correlation between air pollution index and visibility is the most significant, which is-0.37. However, inter-monthly variation of monthly total rainfall, monthly total sunshine duration and API shows obvious reverse phase variation.
