The observations are carried out every three hours. They include measurements and visual observations. All data are 10-minute averages or instantaneous observations at the given time in UTC. During night time – when the weather observer is not on duty - the 3-hourly meteorological observations are performed automatically. Thus, no visual ob­servations are available. All data are generally coded according the definitions of the Word Meteorological Organization WMO (FM12/13) and transferred without delay into the Global Telecommunication System GTS were they contribute for the world wide weather forecasts.

Additionally, all data are archived in the Meteorological Information System at AWI MISAWI which offers an interactive access. A certain access is free for any scientific nonprofit use, see below. For further information please contact Gert König-Langlo.
