GAW Activities in Germany
Activities for the GAW monitoring programme in Germany consist of a co-operation of the German Weather Service, the Federal Environment Agency and a number of research institutes.
The Global station Zugspitze/Hohenpeissenberg consists of the two platforms Zugspitze and Hohenpeissenberg and is operated by the Federal Environment Agency Germany and the German Weather Service. At platform Zugspitze the Federal Environment Agency measures at the Environmental Research Station Schneefernerhaus greenhouse gases, aerosols and chemical reactive atmospheric trace gases. The German Weather Service measures synoptic data, radiation and radioactivity at the Zugspitze summit (2960 m a.s.l.) and at Schneefernerhaus. The measurement program of platform Hohenpeissenberg operated by the German Weather Service includes e.g. reactive atmospheric trace substances, aerosols, ozone profiles, radiation parameters and precipitation. For details on the measurement programs please refer to the respective websites.
The station Zugspitze/Hohenpeissenberg provides the data for central Europe. The next GAW Global Stations are situated in the northwest at the west coast of Ireland, in the north in Finland at the polar circle, in the east at Mount Waliguan in China and in the south in Tamanrasset/Sahara and in Izana on Tenerife/Canary Islands, and in the west on the Jungfraujoch in Switzerland.
The stations on the Hoher Sonnblick in Austria (3100 m a.s.l.), on the Jungfraujoch (3580 m a.s.l.) in Switzerland, and on Hoher Peissenberg (1000 m a.s.l. )Hohenpeissenberg and Zugspitze (2670 m a.s.l.) in Germany, cooperate through the DACH German-Austrian-Swiss and Italian working programme for the joint evaluation of regionally and globally relevant time series and detection and analysis of atmospheric changes in this region.
Measurement activities of the Federal Environment Agency (UBA) at platform Zugspitze
The measurement programme of the Federal Environment Agency includes greenhouse gases and chemically reactive atmospheric trace substances.
- Greenhouse Gases: Carbon dioxide (CO2), Methane (CH4), Nitrous oxide (N2O), Sulfur hexa fluoride (SF6), and halogenated climate forcing trace gases
- Reactive Trace Gases: Ozone (O3), Nitrogen oxides (NO, NO2, NOX, NOy), Peroxy Acetic Nitric Anhydride (PAN), Carbon monoxide (CO), Volatile organic carbons ( < C5) and (>= C5)
- Aerosols: Fine and ultrafine particles, size ranges of fraction concentrations from 10 to 800nm and from 1µm to 20µm, PM10 Beta Absorption, PM10 Mass.
The GAW regional station of Schauinsland is located on a mountain by the same name in the southern Black Forest, about 10 kilometres southeast of Freiburg. Due to its elevation of 1205 metres at the eastern rim of the Upper Rhine Rift, it often lies above the ground-level mixing layer which allows for detection of both long-range transported, and locally influenced, air masses. The station acts as a regional station in the GAW network. Its mainly monitors the greenhouse gases CO, CO2, CH4, N2O, SF6, and the chemically reactive gases ozone, NOx , NO, NO2, PAN, VOC and aerosols, PM10, PM2,5, size ranges of fraction concentrations from 10 to 800 nm.
The GAW regional station Neuglobsow is located in northern Brandenburg, at the southeastern edge of the Brandenburg-Mecklenburg Lake District, right on the southeastern shore of the Stechlinsee lake. The air masses monitored are typical for the eastern region of northern Germany. One of the station’s uses is to serve as a regional station for GAW and monitor the greenhouse gases CO2, CH4, and the reactive gases ozone, NO, NO2.
In keeping with the specific data quality requirements, all data processing steps starting from the acquisition of raw data in the time range of seconds to the production of quality-assured half hour mean values have to be performed at the station. A special software system for data collection and quality assurance at GAW stations was developed in a project commissioned by the Federal Environment Agency under the Environmental Research Plan of the German Environment Ministry. In order to facilitate international standardisation of data processing at GAW stations, developed software components are available to GAW stations free of charge. For further information please refer to „Standardized and automated data quality assurance at GAW Stations: concept, methods and tools“.
