Summary:The invention discloses a method, a device and a system for microwave hyper-spectral clear air scaling. The method comprises the following steps of: setting an atmospheric opacity of a clear air background in a zenith direction; obtaining an atmospheric mean radiant temperature from a database, wherein the atmospheric mean radiant temperature is atmospheric mean radiant temperature of different regions, different months, different frequencies and different elevations; figuring out an atmospheric brightness temperature of the clear air background in the zenith direction according to the atmospheric opacity and the atmospheric mean radiant temperature; obtaining a radiation temperature of a black body scaling source; carrying out two-point scaling according to the atmospheric brightness temperature and the radiation temperature, and figuring out system gains of all channels of a microwave hyper-spectral radiometer; figuring up the atmospheric opacity in all scaling wave velocity irradiation directions according
