The Meteorological Observatory Hohenpeißenberg is the oldest mountain weather station in the world. It is located in the municipality of Hohenpeißenberg, about 60 kilometres southwest of Munich, Germany, and at 977 metres above sea level. Meteorological data is collected on the site continuously since 1781. The measurement series ranks among the longest ever, and was never impacted by urban heat island effects, a problem encountered by the comparably long records from the Basel and Prague observatories. As of today, it is operated by Deutscher Wetterdienst, and takes part in the Global Atmosphere Watch programme.
