We performed a comparative analysis of the estimates of the internal mixing layer height from sodar data against estimates from measurements of altitude-temporal temperature profiles using the meteorological temperature profiler M7V-5. The term "internal mixing layer" is defined as the layer of intense turbulent pulsations. The comparison have shown that the "Volna" sodars are totally capable to record the altitude-temporal behavior of the region of intense turbulent heat exchange with the underlying surface. An algorithm of automatic determination of the internal mixing layer height is proposed for sodars of "Volna" series. Seasonal dynamics of the internal mixing layer is studied by the example of a few-year record.
