This dataset contains time series of turbulent exchange of CO2, heat and momentum measured at two heights at SMEAR I research station in Värriö, Salla, Finland, during years 2012–2021. The flux measurements were done in tower above the forest and at 2.5 m height below the canopy.

The data were exported from SMEAR database on the dataset release date. Most recent version of the data are available at https://smear.avaa.csc.fi/.
