Abstract
A method of measuring reflected radiothermal radiation of the Sun and the Earth from mesospheric clouds is proposed. To substantiate the method, an experiment was performed for measuring laser radiation at the wavelength of 0.52 μm through dielectric plate, with ice 0 sedimented from the gas fraction. In this experiment, intense absorption of probing radiation was discovered at the temperatures from –80 to –23 °C. In a field experiment, a simultaneous rise of radio brightness temperature at ~5 К was recorded at 4 wavelengths of the microwave band.
