An Experimental Setup of Ground-based and Airborne
Systems to Study Spatio-temporal Structures
in Atmosphere-Land Surface Energy, Water
and CO2 Exchange

Exchange processes between land surface, vegetation and
atmosphere over structured, inhomogeneous regions are investigated
in an experimental approach. For that purpose
ground-based long-term monitoring and dedicated campaigns
are combined within the Rur catchment, Germany.
Four campaigns covering different vegetation periods have
been performed with instrumentation ranging from leaf
level gas exchange, eddy correlation stations, scanning remote
sensors to aircraftobservations. Synergistic data analysis
shall reveal spatio-temporal structures in the exchange
processes and their relation to external parameters.
