| Zusammenfassung |
| Carbon dioxide CO2 is the most important greenhouse gas in the earth’s atmosphere. For
understanding and predicting climate change, a thorough and quantitative knowledge of the
natural and anthropogenic processes affecting the atmospheric CO2 concentration on a
global scale is crucial. Many of these processes occur on regional scales, with a
considerable variability depending on local climate, ecosystem and infrastructure.
Thus, detailed process understanding is often gained from investigations on local
scales.
CO2 measurements made in a rural area around Jülich, Germany, on a meteorological
tower at 100 m altitude display typical diurnal and seasonal cycles caused by plant
photosynthetic activity, as well as emission signatures from local anthropogenic sources such
as power plants and traffic. We attempt to quantify these and other CO2 fluxes relevant at our
measurement site in a top-down approach, employing a simple model of meteorological and
transport processes at the local scale. |
