Some peculiarities of interpretation of the atmospheric radiation measurements at short millimeter waves

There are a wide range of measurements of thermal atmospheric radiation at wavelengths λ≅0.5; 0.8; 1.35 cm for obtaining data on the basic meteoelements-on the cloud liquid water content, temperature and humidity content of the atmosphere. Together with this there are the problems of the definition of impurity gas components (O ₃, CO, N₂O, etc.), investigation of the near-ground layers of the atmosphere as well as definition of the small humidity content in extremal climatic conditions (at low temperatures t≲-30°C). To solve the above problems it is reasonable to use measurements of the atmospheric radiation in short-wave region of the millimeter range (the wavelength λ≃1-3 mm) and in the submillimeter one
