Long-Term Meteorological Station Potsdam Telegrafenberg

Mainbuilding, about 1900

The Long-Term Meteorological Station is globally the only meteorological station which can boast of such a comprehensive observation programme going back without gaps over a period of more than 100 years. The data has been proved to be homogeneous. The historical conditions for observation have been kept up until the present day. Among these are the

• unchanged location (the station has not been moved, no changes to the observation site)
• unchanged surroundings
• unchanged methods and rules for observation, unchanged equipment
• time at which data recorded according to mean local time
• recording of values which are not observed elsewhere
• analogue (continuous smoothly varying) recording of the most important meteorological values (see measurement programme)

The station's measurements series are representative for the surrounding region for various spatial and temporal scales.
