Norm values tables

To describe the average climatological conditions at a station long term averages (or norm values) are required. Station tables show the latest set of 30-year averages, covering the period 1981-2010 or the standard period 1961-1990, for different parameters (available as pdf or tab-stop divided text-files). Periodic processing of newly occurring inhomogeneities in the data series may lead to changes in the norm values. The processing status is indicated in the individual documents.

Explanation

  • Days of air frost: the maximum-temperature remains below 0° C.
  • Days of ground frost: the minimum-temperature decreases below 0° C.
  • Summer days: the maximum-temperature amounts to 25° C or more.
  • Heat days: the maximum-temperature amounts to 30° C or more

 

Please note that for each station there is either sunshine duration or cloud cover available. Both parameters complement one another and both provide information on the average sun exposure.
