Abstract EN
Epidemiological studies around the world have reported that fine particulate matter (PM2.5) is closely associated with human health.
The distribution of PM2.5 concentrations is influenced by multiple geographic and socioeconomic factors.
Using a remote-sensing-derived PM2.5 dataset, this paper explores the relationship between PM2.5 concentrations and meteorological parameters and their spatial variance in China for the period 2001–2010.
The spatial variations of the relationships between the annual average PM2.5, the annual average precipitation (AAP), and the annual average temperature (AAT) were evaluated using the Geographically Weighted Regression (GWR) model.
The results indicated that PM2.5 had a strong and stable correlation with meteorological parameters.
In particular, PM2.5 had a negative correlation with precipitation and a positive correlation with temperature.
In addition, the relationship between the variables changed over space, and the strong negative correlation between PM2.5 and the AAP mainly appeared in the warm temperate semihumid region and northern subtropical humid region in 2001 and 2010, with some localized differences.
The strong positive correlation between the PM2.5 and the AAT mainly occurred in the mid-temperate semiarid region, the humid, semihumid, and semiarid warm temperate regions, and the northern subtropical humid region in 2001 and 2010.
