The emission rates of SO

, CO, non-methane volatile organic
carbon (NMVOC), black carbon (BC), and organic carbon (OC) for
the month of March obtained from Ref. 22 are shown in Fig. 2 on

year 2000.
The spatial distribution patterns of SO

(Figs. 2(a),
(b) and (e)) emissions are similar with a maximum exceeding
2000 ton/gird/month over eastern China whereas those of PM
10
and VOC
(Figs. 2(c) and (f)) show a maximum over eastern China and the Indo-
China peninsula where biomass burnings are the main sources.
