Flow: nl/min PAR: µmol SWC: % Tsoil: °C The timestamps are the mean of the measurement period for this chamber Gas concentrations are in ppb The fluxes are available in two formats: mean+sd, and mean and sd in seperate columns In each ecosystem we tried to cover the heterogeneity of the ecosystem (thats indicated under the Ring variable) - Neustift (Austria) is an exception: RO and ROC were drought (RO) and control (ROC) plots of a rain-exclusion experiment (Kitz 2017); F and NF were untreated plots.
