Short summary
A single year’s offline measurement was conducted in Hohhot to reveal the chemical characteristics and sources of PM2.5 in a semi-arid region. We believe that our study makes a significant contribution to the literature because relatively few studies have focused on the chemical composition and sources of PM2.5 with offline measurements. A knowledge gap exists concerning how chemical composition and sources respond to implemented control measures for aerosols, particularly in a semi-arid region.
