Abstract

The results of laboratory measurements of the attenuation coefficient of supercooled water, without scattering, at the frequencies from 140 to 180 GHz and in the temperature range from 0 to -45 °C are presented. The obtained values of the attenuation coefficient have been used to evaluate linear attenuation coefficient both in atmospheric water aerosols and in aerosols consisting of wet solid particles. In the examined range of frequencies, linear attenuation for the liquid water content of 0.1 g/m³ at the temperatures of -40…-45 °C is 1.2…1.5 dB/km.
