Emissions of Condensable Organic Aerosols from Stationary Combustion Sources over Japan.

ABSTRACT: Treatment of condensable particulate matter (CPM) is key for accurate simulation of atmospheric particulate matter (PM), because conventional stationary combustion source emission surveys do not measure CPM in many countries. This study updates previously estimated CPM emissions from stationary combustion sources in Japan by considering the relationship between the CPM fraction and filterable PM (FPM) concentrations for individual sources rather than using a uniform CPM/FPM ratio for all sources. As a result, the total emissions ratio of condensable organic aerosol (OA) and filterable PM_2.5 ( OA CPM ∕ PM 2.5 FPM ) from stationary combustion sources, based on this update, changes from ~2.0 to 0.20, and the estimated concentrations of condensable OA, averaged over winter an
