Abstract:

The results of numerical estimates of the absolute error introduced in measurements of the relative humidity by atmospheric turbulence in the case of vertical two-frequency radioacoustic sounding are presented. The main interfering factors in this case are the decrease in the transverse coherence length in the sound wave and the effect of horizontal atmospheric wind.
The estimates were made for harmonic acoustic frequencies in the band 1-13.6 kHz while sounding in an atmospheric layer 50-200 m under calm conditions and in the presence of a moderate wind. The relative error in the relative humidity of 10-100% does not exceed 10%:when sounding at frequencies of 3.4-6.8 and 6.8-13.6 kHz under calm conditions and at frequencies of 6.8-13.6 kHz in the presence of wind with velocity 5m/s.
