The lowest part of the Earth’s atmosphere, which contains about 80% of the mass of the atmosphere and 99% of its water vapor. The upper boundary of the troposphere is located in the polar latitudes at heights of ~ 8-10 km, in the middle latitudes - at heights of ~ 10-12 km, in the equatorial latitudes - at heights of ~ 16-18 km.

Abstract
The impact of smoke from forest fires in western Siberia on meteorological, atmospheric electric, and aerological variables has been analyzed. The anomalous distribution of water vapor in the atmosphere associated with the peculiarities of the evaporation regime and the absence of advective moisture transfer over the southern regions of Western Siberia during the fires. With an increase in the height of the homogeneous surface smoke layer with an unchanged aerosol optical thickness, the cooling of the earth's surface and heating of the atmosphere was weakened. The smoke plume spreads predominantly in the middle of the troposphere, creating aerosol layers elevated above the ground, the lower part of which had a negative volume charge. The effect of diurnal variations in the electrical field in the near-surface layer, differs from the known similar effects.
