This study explores synergy between ICOS atmospheric and ecosystem networks by utilizing slow-response analysers (~2 sec) on tall atmospheric towers for ecosystem studies using the Eddy Covariance method. A standard setup with an ultrasonic anemometer and an infrared (IR) fast-respons...
Currently the global network called FLUXNET consists of over 150 eddy-covariance flux-tower systems, with most flux towers operating continuously for 4 years or longer. FLUXNET (see http://daac.ornl.gov/fluxnet/) provides scientific coordination and access to consistent flux data to support global...

caused by different environmental conditions at both EC towers. It is concluded that the extension of the two-tower approach can help to receive more reliable uncertainty estimates because systematic differences of measured CO2<\\/sub> fluxes which are not part of random error are filtered out. ...

Modelling data came from five European eddy covariance measurement towers over 2–8 years. The model was tested against independent data from two AmeriFlux stations. The model with the APAR, temperature and VPD modifiers worked well in almost all the site–year combinations, but the SWC modifier ...

system38. If SC was not provided or missing, two cases were implemented: for measurement heights lower than 3 m and short canopies, the SC term was considered to be 0; for taller towers/canopies, a discrete estimation based on the top measurement of CO2concentration was used to compute ...
A global network of long-term CO2 and water vapor flux measurements has existed since the late 1990s (Baldocchi et al., 2001) and flux towers are nowadays organized in continental-scale research infrastructures like the Integrated Carbon Observation System (ICOS) in Europe (Heiskanen et al., ...
