GAWTEC & YESS Webinar Series Reactive Gases: Dagmar Kubistin - Measurements reactive gases at GAW

Anthropogenic emissions, climate change and mitigation strategies alter the composition of trace gases with impact on air quality and climate. Since 1995, the Hohenpeissenberg meteorological observatory operated by the German Meteorological Service (DWD) performs observations of atmospheric key species in Southern Germany within the Global Atmosphere Watch (GAW) program. The atmospheric composition, characteristic for central Europe, has been continuously monitored including reactive gases such as in-situ ozone, nitrogen oxides, carbon monoxide, anthropogenic and biogenic VOCs and total OH reactivity. This presentation will give an overview of the reactive trace gas measurement programme, their observations and interactions and the resulting change of the atmospheric composition at Hohenpeissenberg.
