AB Methodological errors estimation of the air humidity measurement, arising from a priori uncertainty of other meteorological parameters altitude distribution, is made. Their influence on recording vertical profiles of the measured meteorological quantities is estimated using
correlative processing of the received signals of radio acoustic sounding systems. It is shown that for an arbitrary choice of a pair of sounding audio frequencies, the methodical error of measuring relative humidity can reach 100% even with thermal turbulence. The influence of a
wind and sounding wave refractive effects on formation of methodical measurement errors can be reduced by rational selecting technical parameters of the sounding system antenna arrangement.
