Global Monitoring


The group "Global Monitoring" investigates atmospheric composition, variability, budgets and long-term trends of water vapour, ozone and related compounds, and aerosols in the troposphere and lower stratosphere.

Understanding the climate impact of greenhouse gases such as water vapour and ozone and of aerosols in the upper troposphere and lowermost stratosphere (UTLS) is still poor although the greenhouse effect is largely generated in this layer of the atmosphere.

The key tool for our research is the deployment of scientific instruments for routine observations of trace gases and aerosol particles on board of passenger aircraft. This research is performed as part of the new European Research Infrastructure IAGOS in close cooperation with leading research institutes in Germany, France, and the UK, as well as aviation industry and airlines. IAGOS was included in the Roadmap 2006 of the “European Strategy Forum on Research Infrastructures” (ESFRI).

Major research topics

Long term measurements of atmospheric chemical composition onboard of passenger aircraft (IAGOS).

Development of novel instrumentation for compact airborne sensing instruments; best practice protocols for quality assurance and quality control of monitoring data (DENCHAR, IGAS).

World Calibration Centre for ozone sondes as support to global efforts on a harmonization of the world-wide ozone data set (JOSIE).
