five distinct 03 minima. Such events were typically associated with advection of marine polar air
masses. The low burden of aerosols within the accumulation mode coinciding with low ozone mixing
ratios suggests that 03 destruction occurred during long transport times in the remote marine Arctic,
largely in absence of anthropogenic pollutants. It was found that the 03 depletion was restricted to the
boundary layer only. Typically a capping inversion defined the upper limit of its vertical extension.

Abstract: Highly charged water droplets have been used as an ion source to increase the removal rate
of smoke. The change in number concentration for smoke subjected to uncharged and charged
droplets was determined. For charged sprays the number concentration fell by approximately 60%
after five minutes compared with a 10% decrease for an uncharged spray.

Abstract: A series of experiments have been conducted to study the influences of environmental
parameters on the equilibrium factor. Most of them were carried out in a walk-in type chamber. The
deposition velocity was calculated using the Jacobi model. The ranges of the environmental
parameters studied in the experiments are humidity 30 to 90% r.h. and radon concentration 2 to
40 kBqm −3 . The aerosol sources included electric fumigator, mosquito coil, incense, and cigarette
with the particle concentration 2000 to 6500 cm −3 and the attachment rate 10 to 350 h −1 . The results of
the experiment show that the equilibrium factor tends to decrease as the radon concentration
increases. On the other hand, the equilibrium factor tends to increase as the humidity increases, and so
is the increasing attachment rate. Of all the parameters mentioned above, the influence that aerosols
have on the equilibrium factor is the predominant factor. The calculated deposition velocity for the
unattached fraction of radon daughters tends to increase as the radon concentration increases.
However, it tends to decrease as the humidity increases.

Abstract: During the Atlantic Stratocumulus Transition Experiment (ASTEX) in June 1992, two
descents in cloud-free regions allowed comparison of the change in aerosol optical depth as
determined by an onboard total-direct-diffuse radiometer (TDDR) to the change calculated from
measured size-resolved aerosol microphysics and chemistry. Both profiles included a pollution haze
layer from Europe, but the second also included the effect of a Saharan dust layer above the haze. The
separate contributions of supermicrometer (coarse) and submicrometer (fine) aerosol were
determined, and thermal analysis of the pollution haze indicated that the fine aerosol was composed
primarily of a sulfate/water mixture with a refractory soot-like core. The soot core increased the
