Description of EC flux sites
Sikaneva II (bog)
(Contact persons:Pavel Alekseychik, Timo Vesala)
EC fluxes are measured at Siikaneva
bog site in Southern Finland (Siikaneva II). The EC system is located about 3 m above the ground.
A three-axis sonic anemometer/thermometer (USA-1, METEK, Germany) is used to measure three
wind components and air temperature. CO2 and H2O concentrations are measured by
the enclosed-path gas analyser (LI-7200, LI-COR Biosciences, Lincoln, NE, USA), while the open-path
gas analyser Licor 7700 is used for measuring CH4 concentration.
