“…Information about the content of water vapor in the atmosphere and trends in its change is necessary for solving problems of climatology, hydrometeorology, ecology, atmospheric optics (such as forecasting clouds and precipitation 5 , assessing radiation fluxes 6,7 and the propagation of visible and infrared emissions 8 , assessment of greenhouse gases 9 , aerosols 10,11 and ozone production rates 12 , etc. ).…”

The work presents analysis results of trends in the average annual air humidity in the atmospheric boundary layer of Siberia for 1981−2020 according to observations of 24 aerological stations. It has been established that, in contrast to the average air temperature, which is characterized by positive trends throughout the entire atmospheric boundary layer of Siberia, negative trends in the average annual air humidity are observed from a height of 400 m in the south-west of the territory, and they prevail at 1600 m in Western Siberia to the west 7580 E and, partially, in the subpolar and temperate latitudes of Eastern Siberia. Changes in the average annual air humidity for 19812020 were compared with the previously studied period 19812010. The moisture content in the atmospheric boundary layer over Siberia increased almost throughout the region, with the exception of the central areas of Eastern Siberia, where a slowdown in the growth of air humidity is observed.

“…Therefore, the assessment of water vapor trends is of great importance, both at the global and regional levels, and especially in the atmospheric boundary layer (ABL), which accounts for half of its content 4 . Information about the moisture content in the atmosphere and its trends is necessary not only for solving problems of climatology, meteorology, and ecology 5−8 , but also for problems of atmospheric optics [9][10][11][12][13][14][15][16] .…”

The work presents analysis results of trends in the average seasonal air humidity within the atmospheric boundary layer of Siberia over 1981–2020, estimated from the observation data of 24 aerological stations for winter, spring, summer, and fall. It has been established that the summer season makes the greatest contribution to the increase in the average annual air humidity in the atmospheric boundary layer of the region, especially near the earth's surface, and to a lesser extent − spring and fall. Changes in the average seasonal air humidity for 1981–2020 were compared with the previously studied period 1981–2010.

“…The content of water vapor in the atmosphere is much higher than the concentrations of greenhouse gases such as CO 2 and CH 4 , which affect the thermal conditions of the atmosphere and the earth's surface. The absorption of electromagnetic radiation by water vapor affects the radiation balance of the Earth's atmosphere 4 . Water vapor retains heat in the surface layer of the atmosphere, absorbing long-wave radiation in the infrared range leaving the earth's surface 2 .…”

The work presents the analysis results of the air humidity spatiotemporal distribution in the atmospheric boundary layer over Siberia, estimated according to the long-term observations of 24 aerological stations for the period from 1981 to 2020. It is shown that average annual and average seasonal values of humidity in winter, spring and autumn decrease from the southwest towards the northeast of the region. In summer, air humidity decreases from south to north of the Siberia territory. There are humidity inversions throughout Siberia in winter. In spring, ones are observed only in the polar latitudes, and in autumn, there are humidity inversions in the subpolar and temperate latitudes of Eastern Siberia.
