Abstract
Accurate wind analyses using six wind classes and twelve splitting directions were done to deeply evaluate wind conditions on Štítná CzeCOS’s ecosystem station in the Czech Republic. The analysis brings information about contribution of different part of the research-forested area to the measurement of CO2 exchange between the studied ecosystem and atmosphere. Štítná station is located inside of a forest composed of Fagus sylvatica with age 114 years and the forest can be harvested sometime forward. Total of 82 % of the wind contributions speed are in the range of 1.0 - 6.0 m s-1 and the major accumulation of winds comes from SE (9 %), SSE (17 %) and S (14 %); 13 % were calm periods. The obtained information will be useful for evaluate the conditions of the use of the eddy covariance technique in the research area.
