The discovery of ferroelectric ice 0, which exists at low pressures at temperatures below –23 °C, has raised the problem of its detection in the atmosphere and on the Earth’s surface. A unique feature of ice 0 is the formation of ultra-thin highly conductive layers at its contact with other dielectrics, where strong scattering and absorption of electromagnetic radiation occurs. This effect may arise due to the emergence of plasmonic mode resonances in small regions of ice structures containing ferroelectric ice 0. This paper presents the results of studies on the thermal radiation of fog over the open water surface of Lake Kenon near the warm water discharge from Chita-1 Power Plant. Measurements were carried out using microwave radiometers at wavelengths of 2.3, 1.35, 0.88 cm and an IR radiometer in the range of 8–12 μm. Daily observations of thermal radiation from the fog cloud were conducted with ground-based instrument setups oriented at an angle of approximately 10–12 ° to the horizontal plane. In winter, during water discharge into the reservoir and formation of a pronounced fog cloud, a sharp change in brightness temperature and radiation temperature was observed, which is associated with the appearance of small ice particles containing ice 0.
Keywords: fogs, radio brightness temperature, radiation temperature, plasmon resonance
