Abstract：This paper studies the influence of the atmosphere channel on 1-10GHz signal. The effects of rain and snow, oxygen, water vapor, clouds and ionospheric scintillation on the meteorological satellite downlink signal mainly include energy loss, according to analyze the impact of the physical environment of atmospheric space on wireless signals. Accordingly, this loss can be solved by increasing the link power budget designing meteorological communication systems. The clouds as the main obstacle in the atmosphere channel will cause multipath signal effects and shadow effects. In order to describe these effects, the appropriate statistical channel model based on specific physical characteristics channel is established and the numerical simulation experiments are carried out. By the results of analyzing atmospheric channel characteristics, and the different types of losses suffered of signal at different atmospheric stratification, the division scheme of the channel characteristics is given. That provides a technical basis to establish wireless channel simulation model.
