摘要: The neutral atmosphere is characterized for the frequency range from 1 to 300 GHz as a nonturbulent propagation medium. Attenuation and delay effects are predicted meteorological data sets: pressure, temperature, humidity, suspended particle concentration, rain rate. physical base of model consists four terms: (a) resonance information 30 water vapor 48 oxygen absorption lines in form intensity coefficients center each line; (b) composite (oxygen, vapor, nitrogen) continuum spectrum; (c) hydrosol attenuation term haze, fog, ,and cloud conditions; (d) model. Oxygen extend into mesosphere, where they behave complicated manner due Zeeman effect. geomagnetic field strength H required an additional input parameter. Each 02 line splits proportionally with numerous, sub-lines, which juxtaposed pattern spread over megahertz scale. Patterns three main polarization cases calculated. Detailed examples atmospheres provide basic millimeter wave height 0 100 km atmosphere.
