Preliminary study of radio astronomical lines effect of rain below 2.9 GHZ

An appropriate site selection for radio astronomy observation is very important in order to find a low level site in RFI value. The aim of this study is to select the best possible factors for astronomical observation sites. There are many factors such as slope, raindrop, river, population density,...
