View of the Max Planck Institute for Biogeochemistry from the west side, the rear view, so to speak. In the middle is the weather station mast, where sensors are often mounted for testing and comparative measurements. In the background are the core mountains.

Jena Beutenberg (Germany)

Meteorological Station on the roof of the MPI for Biogeochemistry on the Beutenberg Campus in Jena

Description & History

The sensors of the meteorological station of the MPI for Biogeochemistry at Beutenberg are located on a 10 m high stainless steel mast. This is equipped with various sensors for temperature, humidity, pressure, wind speed, wind direction, solar radiation, PAR, precipitation amount including precipitation types, CO2 concentration and a web camera. Soil temperature and soil moisture data are collected on the experimental plots behind the greenhouse (see Weather).

The mast is also used for comparative measurements of sensors and instruments and is also used for rescue exercises, by all staff working on masts and towers of up to 300 m.
