Resolution
Spatial aggregation: lake
Temporal resolution of input data: climate variables: daily
Additional temporal resolution information: The model needs daily air temperature data, which can be provided by daily observed/modeled values or reconstructed through daily interpolation of coarser resolution averages (e.g., weekly, monthly)
Input data
Simulated atmospheric climate data sets used: IPSL-CM5A-LR, HadGEM2-ES, GFDL-ESM2M, MIROC5
Observed atmospheric climate data sets used: EWEMBI
Climate variables: tas
Spin-up
Was a spin-up performed?: Yes
Spin-up design: The first year of each simulation period was run starting from LSWT at 4°C, and the LSWT at the end of this period was used to initialize the simulation runs.
Vegetation
Is co2 fertilisation accounted for?: No
Calibration
Was the model calibrated?: Yes
Which years were used for calibration?: Dependent on experiment period and period covered by water temperature observations
Which dataset was used for calibration?: Dependent on experiment period
