Research on the atmospheric attenuation of THz wave at any heights based on fitting method

The atmospheric attenuation of THz wave is closely related to the weather condition, region height and meteorological parameter. In this paper, the discrete data from China Meteorological Data Sharing Service System is employed and then different fitting functions are suggested to fit these discrete data of heights, air pressure, temperature and dew points. Take Wuhan (114.2°E, 30.86°N) for example, the atmospheric parameter at any heights is retrieved in detailed, based on which the atmospheric attenuation of THz wave at different heights is calculated according to recommendation given by the International Telecommunication Union Radio communication Sector.
