Vertical changes of PM driven by meteorology in the atmospheric boundary layer during a heavy air pollution event in central China.

Regional PM transport is a crucial factor affecting air quality, and the meteorological mechanism in the atmospheric boundary layer (ABL) has not been fully understood over the receptor region in the regional transport of air pollutants.
