Abstract
Monitoring is a continuous process of observing and registering the parameters of an object, in comparison with specified criteria. In recent decades, questions related to changes in climatic characteristics have been of great interest. Since 2007, microclimatic observations have been carried out automatically in the mountain-depression landscapes of the Baikal region. The correctness of the use of atmospheric-soil measuring systems is shown by comparing the data of automatic measurements and the data of standard meteorological instruments used at the weather stations of Roshydromet. Estimates of the temperature and humidity regime of air and soils were obtained at 72 sites located in different landscapes in the altitude range of 450–2300 m above sea level. The influence of landscape characteristics, primarily altitudinal zonality, is manifested in the monthly and annual values of meteorological characteristics. Calculations of the vertical gradient of air temperature on the slopes of the mountains are carried out. As a result, an assessment was made of the characteristics of temperature inversions, a phenomenon unique in its power in Eastern Siberia. Their intensity, duration, and frequency were estimated. A comparison is made of the temperature regime of soils under natural and anthropogenically disturbed conditions. The obtained measurement data are used to validate the results of climate modeling and remote sensing (satellite images). The best convergence of rows is observed in open, moderately humid areas. Microclimatic observation data make it possible to study in detail the temperature and humidity regime of landscapes, taking into account the altitudinal zonality, exposure and steepness of slopes throughout the year. The observational data obtained make it possible to clarify the climatic description of the study area, which is currently based mainly on the data of weather stations, the network of which does not cover mountainous regions.
