China different heights annually THz wave atmospheric absorption calculation

摘要

The quantitative calculation of THz wave atmospheric absorption attenuation, especially at actually region's different heights, are always been fundamental and key technology application for variety terahertz communication modes, such as wideband & high-speed network, astro-satellite communication, altitude aero-craft communication, long distance vast data transfer, short range wireless security communication etc. In this paper, the 2012 annually reanalysis data selected from National Centers for Environmental Prediction (NCEP) is employing to calculate the China region THz wave statistical monthly atmospheric absorption attenuation at different heights. Optimal Spline-3 function fitting method is using to fit NCEP discrete meteorological data into continuous curves. Based on Millimeter Propagation Model (MPM) as well as ITU Recommendation, the paper made China 2012 monthly barometric pressure, temperature, relative humidity curves, and different heights THz wave Oxygen and water vapor absorption comparison to get China region's statistical THz wave atmospheric absorption universal principles.
