For carrier frequencies above 10 GHz, rain will degrade performance. The following three different mechanisms contribute to this degradation.
2. An increase in sky noise temperature
3. Interference from adjacent channels when polarization is used for frequency reuse. This is caused by depolarization.
Each of these sources of degradation is calculated in the sections here, followed by a discussion of how each affects performance.
