Characteristics of PM_2.5 Concentrations across Beijing during 2013-2015.

ABSTRACT: High concentrations of particulate matter (PM_2.5) and frequent air pollution episodes in Beijing have attracted widespread attention. This paper utilizes data from the new air pollution network in China to examine the current spatial and temporal variability of PM_2.5 at 12 monitoring sites in Beijing over a recent 2-year period (April 2013) to March 2015). The long term (2-year) average concentration was 83 µg·m^-3, well above Chinese and international standards. Across the region, annual average concentrations varied by 20 µg·m^-3 (25% of the average level), with lower levels in suburban areas compared to periurban and urban areas, which had similar concentrations. The spatial variation in PM_2.5 concentrations was associated with severa
