Afforestation-related fertilisation quickly turns barren cutaway peatland into a carbon dioxide sink

Energy peat extraction has declined rapidly in Europe in recent years, leaving thousands of hectares of land requiring after-use management and planning. A popular after-use option, afforestation, is understudied, and there is a limited understanding of its overall effect on greenhouse gas (GHG) and energy exchange. In this study, we present a multi-year record of eddy covariance fluxes of carbon dioxide (CO2), energy fluxe,s and surface albedo, chamber measurements of methane (CH4) and (N2O), and estimates of lateral carbon (C) losses from dissolved organic carbon (DOC) measurements from a cutaway peatland in Finland during the first three years of afforestation. The site was fertilised with wood ash, and 2-year-old Scots pine (Pinus sylvestris) saplings were planted. Wild vegetation emerged at the site in the first summer after fertilisation. Satellite-derived leaf area index data showed clear year-on-year increase, and there was good agreement with changes in CO2 fluxes over the full..., , # Data from: Afforestation-related fertilisation quickly turns barren cutaway peatland into a carbon dioxide sink

This dataset contains measurements from Naarasneva, a former peat extraction site in Finland that is being afforested. In this dataset there are eddy covariance fluxes, chamber flux measurements, dissolved organic carbon concentration measurements and estimates of export, and satellite-derived observations of LAI and NDVI. The dataset covers the time period 2021 to 2024.

Data are separated into different folders within `nsv_data.zip`. Each folder has its own ReadMe that explains the files in more detail.
