Description

The data contains daily mean N2O fluxes and supporting environmental data from June 2015 to September 2019. The measurement site is Lettosuo peatland forest (ICOS associate site, FI-Let) located in Tammela, Finland. The site is nutrient-rich and drained for forestry in 1969. Light selection harvest was done at the automatic chamber location in March 2016. Six automatic chambers operated year-round and each chamber measured N2O flux once in an hour. Environmental variables were measured close to the automatic chambers or in the nearest automatic weather station. For more information about the site and automatic chamber system, see Koskinen et al., (2014) and Korkiakoski et al. (2017, 2020).
