Systematic measurement results of aerosol dispersity in the size range
from 0.004 to 10 mu m in diameter, element composition, and the mobil
ity spectrum of atmospheric ions in the range from 0.00032 to 5 cm(2)/
V s in the surface atmospheric layer at Zigler Island (Western Arctic,
Franz-Joseph Archipelago, March-April 1994) are presented. A comparis
on is made with data obtained using similar methods and instruments at
Wrangel Island (Eastern Arctic, March-April 1985), in Antarctica (Mol
odezhnaya station, January-May 1983), over the Pamir mountains (Fedche
nko glacier, September 1989) and in the vicinity of Moscow (Obninsk, A
pril-May 1994). The form and variability of the aerosol size and air i
on mobility spectra at different regions of the Arctic and Antarctic,
as well as in mountain and forest steppe regions, do not differ signif
icantly. The stratification of the atmospheric boundary layer and wind
speed are the main factors of variability of the arctic aerosols and
ions. Inflows of air from the mainland do not change these positions.
