Turbulent fluxes of carbonyl sulfide(COS) and carbon disulfide (CS2) were measured over a spruce forest inCentral Germany using the relaxed eddy accumulation (REA) technique. A REA sampler was developed and validated usingsimultaneous measurements of CO2 fluxes by REA and by eddy correlation. REA measurements were conducted during six campaignscovering spring, summer, and fall between 1997 and 1999. Both uptake and emission ofCOS and CS2 by the forest were observed, with deposition occurring mainly during the sunlitperiod and emission mainly during the dark period. On the average, however, the forest acts as a sink for both gases. The averagefluxes for COS and CS2 are  -93 ± 11.7 pmol m-2s-1 and  -18 ± 7.6 pmol m-2 s-1, respectively. The fluxes ofboth gases appear to be correlated to photosynthetically active radiation and to theCO2 and chem{H_2O} fluxes, supporting the idea that the air-vegetation exchange of both gasesis controlled by stomata. An uptake ratio COS/CO2 of 10 ± 1.7pmol <fontface="Symbol">mmol-1 has been derived from the regression line for the correlation between theCOS and CO2 fluxes. This uptake ratio, if representative for theglobal terrestrial net primary production, would correspond to a sink of2.3 ± 0.5 Tg COS yr-1
