AB: Recent progress in global change research has shown clearly that the Earth's environment is a complex system, defined through intricately linked processes, feedbacks and teleconnections. This integral perspective renders obsolete the conventional scientific approach of investigating disjunct causal relationships, and demands a new, integrated way of conducting environmental Earth research. To reflect this approach to Earth System Science, the new IGBP core project "Integrated Land Ecosystem - Atmosphere Processes Study" (iLEAPS) has been designed to study the interactions between land and atmosphere within the Earth System. The fundamental objective of iLEAPS is to provide understanding of how interacting physical, chemical, and biological processes transport and transform energy and matter through the land-atmosphere interface, particularly emphasizing interactions and feedbacks at all scales - from past to future and from local to global. The research planned for iLEAPS covers the basic processes that link surface-atmosphere exchange with vegetation/ecosystem processes on the one hand and with atmospheric dynamics, tropospheric chemistry and physical climate on the other. There will be four foci: 1) Land-atmosphere exchange of reactive and conservative compounds: Key interactions and feedbacks in the Earth System 2) Feedbacks between land biota, aerosols and atmospheric composition in the climate system. (a) Biosphere-aerosol-cloud-climate interactions, (b) Surface-atmosphere exchanges and the self-cleansing mechanism of the atmosphere 3) Feedbacks and teleconnections in the land surface -vegetation- water - atmosphere-system 4) Transfer of material and energy in the soil/canopy/boundary-layer system: Measurements and modelling
