Other claims from this paper (6)
- Method / resource The model ensemble median underestimated wheat water use in all evaluated environments.
- Association Relative underestimation of daily ET was constant across atmospheric evaporative demand levels.
- Association Absolute ET error was greater on days of larger evaporative demand.
- Method / resource Potential versus reference crop ET approach did not explain relative model performance.
- Association Simulated leaf area index errors were associated with daily simulated ET errors, varying by growth stage.
- Recommendation The authors recommend improving simulation of atmospheric ET demand.
