Temporal variations of dust concentration
Figure 2 shows the time series of modeled PM
10
concentrations of Asian
dust averaged for the layers below 100 m, 100-1500 m and above 1500 m, as
estimated by the ADAM model. The mean-surface anthropogenic aerosol
concentration is estimated by the aerosol dynamic model
12
with obser-
vations of PM
10
concentration at several sites in South Korea (Fig. 1).
The present ADAM model simulates quite well the temporal variation of
the PM
10
concentration of more than 1000
µ
g/m
3
during the Asian dust
period at all sites. The starting and ending time of Asian dust and the
timing of the maximum PM
10
concentration simulated with ADAM are
in good agreement with the observations at all sites over South Korea
(Fig. 2).
