Возможности измерения влажности акустическими системами зондирования атмосферы

Abstract

The multi-frequency method of measuring the relative humidity of the atmosphere with sodars is justified. Based on the experimental data, the methods of extra- and interpolation obtained the values of the sound absorption coefficient for a wide range of frequencies, temperatures and humidity. The research results confirm the possibility of determining the humidity of the air at a selected height by comparing the values of the powers of the received signals at two frequencies of acoustic sounding.
