Abstract: Within the experiment, a permanent temperate grassland is treated with elevated CO2 (~20% during daylight hours). In three rings the air is enriched with CO2 while other three rings act under atmospheric CO2 (control). This dataset contains the ring-wise late-summer yields as well as the ring-wise CO2 concentrations (averaged in the three months before harvest) and other variables describing the environmental conditions (likewise aggregated to their average in the three months preceding harvest; respectively sum for solar radiation and precipitation). Additional info: The dataset is also available within the CRAN R pa... Additional info: The dataset is also available within the CRAN R package ("msaFACE"). Here, the ring-wise variables can be used as dependent and independent variables while the environmental variables can be used to derive the subsets (where regression within the Moving Subset is performed) and be plotted to get a clear picture of the environmental conditions within the respective subset.
