During a 3-year-period rain intensity was sampled continuously in 1 min-intervals. The relation between short and long term averages of rain intensity is given. Rain attenuation on a 12.2 GHz-radio link was recorded simultaneously with point rainfall rate. Both are related following a method proposal by LIN in 1975. It is shown that data on rainfall rate alone may form a sufficient basis for the design of radio links at frequencies above 10 GHz.
