Method / resource Model uncertainty averaged 15% higher at low input than high input sites.
Method / resource Low versus high input sites differed more in uncertainty for evapotranspiration, nitrogen uptake and water use efficiency than dry matter.
Method / resource At least five partially calibrated models were needed to keep ensemble variability below field variation.
Method / resource At least three fully calibrated models were needed to keep ensemble variability below field variation.
Observation Carbon dioxide change did not influence model variation.
Method / resource Temperature or rainfall departures from historical levels raised yield model variation as much as 41%.
Method / resource Temperature or rainfall departures raised evapotranspiration model variation as much as 23%.
Observation Temperature increases accounted for the most uncertainty among the climate factors.
Method / resource Median ensemble potato yield rose on average 6% per 100 ppm carbon dioxide increase.
Method / resource Median ensemble potato yield fell 4.6% per °C temperature increase.
Method / resource Different representations of light utilization produced significantly different predictions.
