Effects of land-use changes on sources, sinks and fluxes of carbon in European mountain areas.

The NEE determined with the eddy covariance method is characteristic for two ecosystems (intensively managed and abandoned grasslands at Rigi-Seebodenalp), and provided information on its long-term carbon source or sink relationship.

The driving variables photosynthetic active radiation (PAR), temperature (T), humidity (VPD), soil water potential (Ysoil), and nutrient availability (nitrogen), were recorded along with the EC measurements.

This data set allowed analyzing the contribution of each variable to the NEE, and was essential for ecosystem carbon exchange modeling.
