Eddy Covariance
Eddy Covariance (H2O/CO2), surrounding area
The site is situated far from major human buildings or structures within a largely undisturbed patch of tundra. The downside of this is it is also far from any electricity network. Hence, one of the key challenges of the project has been to design a reliable, self-sufficient power supply, which allows continuous operation of the system even during the polar night. We currently rely on a combination of solar power and wind generators.
Eddy Covariance (H2O/CO2), set-up
In March 2007, we set up an open path eddy covariance system in the vicinity of the existing Bayelva station in Spitsbergen to start a long-term measurement record. The system is capable of measuring fluxes of sensible heat, water vapour and thus latent heat, as well as CO2. It consists of a CSAT3 sonic anemometer, a CS7500 open path CO2 and H2O gas analyzer and a SR50 sonic ranging sensor to measure snow depth around the unit.
Other meteorological parameters are measured at the long term climate and soil stations near the Eddy Covariance System (see Bayelva soil and climate station).
