Abstract
In this study, the direct radiative forcing (DRF) of atmospheric black carbon (BC) over East Asia, with the focus on the Korean Peninsula region, is estimated. An air quality model, composed of a meteorological model and a chemistry transport model, is used to simulate the emission and transport of BC aerosols. The spatial distribution of BC obtained by air quality modelling is then used to estimate the BC DRF utilizing a parameterization taking into account the meteorological conditions and the surface characteristics. The warming effect of BC over Korean Peninsula region estimated in this way is compared with those of greenhouse gases. The BC DRF estimated for this region is shown to be similar to the globally estimated levels appearing in the literature, although observations and modelling for different seasons are required to validate the estimation further.

This study was supported by the CEFV (Center for Environmentally Friendly Vehicle) of Eco-STAR project from MOE (Ministry of Environment, Republic of Korea).
