Comparative Study of Radiative and Carbon Fluxes at Three Ecosystems in Germany, Canada and Costa Rica (ComRadE)


Our understanding of forest ecosystem processes such as energy and carbon exchange is limited. The fraction of absorbed photosynthetically active radiation (FAPAR) by forest canopies is a crucial variable for assessing global carbon balances and currently there is an urgent need for reference data to validate satellite-derived FAPAR products. Overall, there exist only few studies combining radiation quantity, quality and carbon fluxes in forest ecosystems, despite the necessity of reliable data and process understanding as input for biogeochemical models under the aspect of ongoing climatic change. The project ComRadE will provide insights associated to carbon and energy fluxes in a boreal, a temperate, and a tropical dry forest. It will also initiate a long-term collaboration between the involved institutes of the RWTH Aachen University (LFG Physical Geography and Climatology), the University of Alberta (Alberta Centre for Earth Observation Sciences) and the Research Center Jülich (Agrosphere Institute IBG-3) including the establishment of a long-term coordinated environmental measurement program of radiative fluxes.
