Return levels for precipitation of six hours at weather stations in different parts of Finland. With the help of the table it is possible to examine precipitation (in millimetres) which has a frequency (return period) of either 10, 20, 50, 100 or 500 years. The table shows the best estimate (average - avg.) and the limits within which 95% of cases occur. Empty cell means that the method used was not applicable for estimating the return levels in question.
