“…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.…”

“…For the analysis, we used the results of measurement by ground-based remote sounding the atmosphere by the temperature and wind profiling complex, consisting of the meteorological temperature profiler MTP-5 (MWR) [22] and the acoustic meteorological locator Volna-4M (sodar) [27]. The complex was located on the territory of the Basic Experimental Complex of the V.E.…”

“…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.

“…For more details about the measurement site and instrumentation characteristics, see, for example, [17]. According to the estimates reported in [20], at the BEO site under favorable conditions (low external noise level, alight wind, no precipitation, etc. ), the sodar is capable of recording signals from distances up to several hundred meters with u (smaller than 0.1 m/s in 90% of cases).…”
