Zusammenfassung |
Exchange of non-CO2 trace gases between the land surface and the
atmosphere plays an important role in atmospheric chemistry and climate.
Recent studies have highlighted its importance for interpretation of
glacial-interglacial ice-core records, the simulation of the pre-industrial
and present atmosphere, and the potential for large climate-chemistry and
climate-aerosol feedbacks in the coming century. However, spatial and
temporal variations in trace gas emissions and the magnitude of future
feedbacks are a major source of uncertainty in atmospheric chemistry, air
quality and climate science. To reduce such uncertainties Dynamic Global
Vegetation Models (DGVMs) are currently being expanded to mechanistically
represent processes relevant to non-CO2 trace gas exchange between land
biota and the atmosphere. In this paper we present a review of important
non-CO2 trace gas emissions, the state-of-the-art in DGVM modelling of
processes regulating these emissions, identify key uncertainties for global
scale model applications, and discuss a methodology for model integration
and evaluation. |
