Meteorological Tower

Mentor: J.H. Schween


The meteorological tower was built in 1963 and 1964 based on the model of the towers in Rookhaven (USA) and Risoe (Denmark). It has a height of 124 m and a triangular cross section. An elevator inside is operated for easy access to the measurement platforms. The tower is steadied from three directions at 40 m and 100 m height respectively.

The tower is located in the northwest of the Jülich Research Center and surrounded by 20 m high forest. The instrumentation allows measurements of wind velocity, temperature and humidity in 8 heights, wind direction in 3 heights and radiation in two heights to provide the local information on wind, air temperature, relative humidty, radiation, and air pressure. Additionally precipitation is registered at ground level.

For more information refer to the webpage at the research center Juelich.

Examples of latest available measurements (typically the last week Friday to Thursday):

T_air RH Wind

Temperature (left, red), humidity (middle, green) and wind (right, blue) measured at different heights (i.e. 2, 10, 20, 30, 50, 80, 100, 120m) the brighter the color the higher up.


We have data available from 1.1.2006. Nevertheless measurements go back to 1961 and the website at Juelich provides Climate data, diagrams, 'meteograms' etc. (in German).
