===Summit observatory===
The summit observatory, which is located at an altitude of {{convert|1782|m|ft}}, is an important scientific measuring station operated by the Institute for Meteorology and Climate Research of [[Karlsruhe Institute of Technology]]. Since 1972 it has measured a variety of atmospheric and climatic phenomena, including the levels of [[ozone]], [[nitric oxide]], [[sulphur dioxide]] and various [[hydrocarbon]]s in the atmosphere as well as meteorological data such as the levels of temperature, [[dew point]], [[relative humidity]], pressure, wind, global and direct irradiance. It became part of the [[World Meteorological Organization]]'s Background Air Pollution Monitoring Network in 1982.<ref name="Slemr">F. Slemr, H. E.
