Description

This package contains data from a drained agricultural boreal peatland for grass silage in Northern Finland. The field, located in Ruukki (N64°41.039' E25°6.379'), has a shallow peat depth of 15-30cm. Eddy-covariance measurements cover the period 5th of November 2019 to 31st December 2021. EC_CO2_fluxes.csv contains the gapfilled 30-min mean CO2 fluxes (NEE) and its components (GPP and respiration). EC_N2O_fluxes_v2.csv contains the ungapfilled 30-min mean N2O fluxes, friction velocity and limit of detection. Metadata.csv contains the 30-min means of meteorological and soil variables from the site. Daily_precipitation.csv contains the daily sums of precipitation. Field_management.csv contains information on field management events (fertilization, harvest etc.).

Supplemental information
The update only concerns the former file "EC_N2O_fluxes.csv". An error was detected in the filtering process of N2O fluxes. In the previous version, the instrument pressure of the N2O instrument (LGR-CW- 244 QCL N2O/CO-23d) was not filtered with its own limit but instead was filtered with the limit set for the CO2 instrument (LI-7200). The correction resulted in having more data available for N2O fluxes (+89 half-hourly N2O fluxes). We also added the limit of detection for every half-hourly N2O fluxes in the updated N2O file (EC_N2O_fluxes_v2.csv).
