“…The effect of overlapping temperature inversions in the 0-1 km PBL layer by turbulent heat exchange is characteristic not only for the warm season, which is represent in this work, but also in winter with long-term implementation of stable stratification. This has been demonstrated in our publications [27,28]. Therefore, it follows that the temperature inversion in the PBL layer 0-1 km can exist when it is completely covered by turbulent heat exchange if the normalized intensity of the inversion ΔTi/ΔHi (°C/m) is less (very approximately) 0.015 °C/m.…”

“…PBL cannot be measured directly [1] but can be determined using different instruments and methods. For this task, the results of the measurements of optical instruments [2][3][4][5][6][7][8][9][10], radiosondes [4][5][6][11][12][13], manned and unmanned aircraft systems [14][15][16][17], meteorological microwave temperature profilers [1,10,[18][19][20][21][22], acoustic sounding (sodar) [23][24][25][26][27][28] and other tools have been used. A list of which can be found in [4,14,29,30].…”

The height of the mixing layer is a significant parameter for describing the dynamics of the planetary boundary layer (PBL), especially for air quality control and for the parametrizations in numerical modeling. The problem is that the heights of the mixing layer cannot be measured directly. The values of this parameter are depending both on the applied algorithms for calculation and on the measuring instruments which have been used by the data source. To determine the height of a layer of intense turbulent heat exchange, data were used from acoustic meteorological locator (sodar) and from a passive single-channel scanning microwave radiometer MTP-5 (MWR) to measure the temperature profile in a layer of up to 1 km. Sodar can provide information on the structure of temperature turbulence in the PBL directly. These data have been compared with the mixing layer height calculated with the Parcel method by using the MTP-5 data. For the analysis, July and September 2020 were selected in the city of Tomsk in Siberia as characteristic periods of mid-summer and the transition period to autumn. The measurement results, calculations and inter-comparisons are shown and discussed in this work. During temperature inversions in the boundary layer, it was observed that turbulent heat transfer (increased dispersion of air temperature) is covering the inversion layers and the overlying ones. Moreover, this phenomenon is not only occurring during the morning destruction of inversions, but also in the process of their formation and development.

The results of calculations of meteorological parameters and atmospheric air quality during abnormally cold weather (T below -20 o C) in Tomsk are presented. These results were obtained using a complex of WRF/CAMx models. The calculation results are compared with observations of ultrasonic meteo stations and temperature profiler of the Joint Usage Centre (JUC) «Atmosphere» and observations of TOR-station of the IAO SB RAS. The adapted Common Air Quality Index (Citeair II project, supported by the EU) calculated by hourly predicted concentrations is used to evaluate the level of atmospheric pollution.
