3 Fluxes between the atmosphere and ecosystems

Donnerstag, 10:00-16:30, H17

Biosphere-atmosphere fluxes are largely controlled by changes in environmental conditions, atmospheric composition (CO2 concentration, N deposition) and human interventions such as fertilization, ploughing or irrigation. Though interdependencies have been established for a number of individual sites, there is still a lack of cross system analysis unraveling commonalities or identifying major differences between terrestrial ecosystems in different climate zones. Moreover, research in biosphere-atmosphere exchange processes has largely focused on temperate regions, while information for tropical and subtropical regions, where major changes in landuse and land management occur, remains scarce. We are looking for studies tackling cross system comparison and innovative instrumental or methodical approaches aiming at quantifying ecosystem-atmosphere exchange processes.
