Abstract

A method of active microwave measurements of near-surface aerosol is proposed, aimed at discovering formation of ice 0 in it. This ice is formed, when water temperature proves to be below –23 °C. Its deep supercooling may occur in media having pores of nanometric sizes, for example, in aerosol particles. As ice 0 contacts dielectric, a double electric layer emerges, having high electric conductivity, exceeding the electric conductivity of the contacting media by many orders of magnitude. As a result, the effects of scattering of electromagnetic radiation increase sharply on accumulations of particles, and it becomes possible to detect such formations in different bands, including the IR-band. The proposed method of detecting scattered electromagnetic radiation in cold aerosol caused by formation of ice 0 in it has started.
