The moisture content of the troposphere above the point of observation of Ust-Barguzin in the period from 2013 to 2017 is considered. To study the moisture content of the troposphere, the data of surface meteorological measurements as well as vertical atmospheric profiling carried out by radiosonde and satellite soundings of the NOAA polar-orbital system are used. Results of vertical profiling allow obtaining meteorological data at different altitude levels. The regression of the dependence of the values of the weighted «mean temperature” on the aqueous tension on the values of the surface air temperature for Ust-Barguzin according to soundings for 2013–2017 is revealed. The parameters of the total zenith tropospheric delay (ZTD) which is the sum of «dry» or hydrostatic (ZHD) and «wet» (ZWD) components are calculated. The values of ZWD determine the amount of integrated water vapor (IWV) and the amount of potentially precipitated water (PW) above the observation point. The possibility of obtaining initial data for creating new numerical models of zenith tropospheric delay and integrated precipitated water vapor for meteorological problems is considered.
