Comparison of microwave path lengths between temperate and tropical region based on effects of rain

Rain is a major source of attenuation for microwave propagation above 7 GHz. The problem of rain attenuation prediction has been studied along the years. In spite of the e®ort developed in di®erent parts of the world, there are yet some points to be clari¯ed. This problem is quite di±cult to be sol...
