Atmospheric Organic Carbon and Elemental Carbon in a Typical Semi-arid Area of Northeastern China in Spring
We present the 24-hour PM2.5 observations that are associated with carbonaceous species at a typical site over a semi-arid region in the northern China during the spring of 2006. The objectives of this study are (1) to investigate the compositions and sources of carbonaceous aerosols in fine particles and evaluate the OC and EC fractions for Asian dust; (2) to investigate daily variations of highly absorbing aerosols (EC and dust) and OC; (3) to identify the transport pathways and possible sources for the carbonaceous aerosols; and, finally, (4) to estimate SOC with respect to transport time and direction in this region during the spring period. This study provides the spatial distribution of fine particles in northern China and evaluates the impact of this distribution on the regional environment.
