This dataset contains time series of meteorology, water quality and turbulent exchange of CO2, CH4, heat and momentum measured at SMEAR II Lake Kuivajärvi site near Hyytiälä Forestry Field Station, Juupajoki, Finland during years 2012–2018.

Soil CO2, N2O and N2O fluxes, soil and litter parameters and meteorological data from a temperate upland forest along a land inclination gradient used in the publication: Gillespie et al. (in press) Land inclination controls CO2 and N2O fluxes, but not CH4 uptake, from a 1 temperate upland forest soil

This dataset contains time series of turbulent exchange of CO2, heat, momentum, O3 and particles measured at two heights at SMEAR II research station near Hyytiälä Forestry Field Station, Juupajoki, Finland, during years 1997–2018. The flux measurements were done with several measurement setups above the forest and at 3 m height below the canopy.
