Description / Abstract: This is by estimating percentiles and means of the frequency distribution of measurements of characteristics. The application to the estimation of means is restricted to certain cases. The procedure enables results which are independent of the actual meteorological conditions prevailing during the interval of time of measurement to be calculated for a longer time.
