Over recent years, it has become increasingly apparent that climate change, air pollution changes and terrestrial surface-atmosphere exchange processes need to be considered jointly for improved attribution and projections of human-caused changes in the earth system. Exchange processes at the land surface come into play in this context because many compounds that either act as greenhouse gases, as pollutant precursors, or both, have not only anthropogenic but also terrestrial sources and sinks. And since the fluxes of multiple gases and particulate matter between the terrestrial biota and the atmosphere are directly or indirectly coupled to vegetation and soil carbon, nutrient and water balances, quantification of their geographic patterns or changes over time requires due consideration of the underlying biological processes. In my presentation I will highlight a number of critical aspects and recent progress in this respect, identifying in particular a number of areas where studies have shown that accounting for ecological process understanding can alter global model projections of land-atmosphere interactions substantially.
