Model toolbox developement
Three models (COUP, LPJ-GUESS and JULES) were considered in ExpeER. Each can be used to analyse ecosystem processes and functioning and thus are valuable tools for ecosystem experiments. The three models have different strengths (Table). The models were applied to more than 1000 gridcells across a N-S and E-W gradient in Europe, as well as at all ExpeER sites, using globally available datasets for each grid cell. At five sites, models were applied to use site-specific data for specific hypothesis testing. The toolbox includes tutorials as well as example output from model runs (Figure).
