Recent progress of research on tropospheric propagation in China

The troposphere, have important effects on the performance of radio systems, e.g. rain attenuation is the main impairment for radio communication systems operating at frequencies above 10 GHz, and tropospheric delay is one of the major error sources for satellite navigation systems (such as GPS), etc. Therefore for the proper planning of radio systems it is necessary to have appropriate tropospheric propagation data and prediction techniques. In this paper, recent research advancements are introduced on radio meteorology, radio wave propagation and remote sensing in troposphere in China.
