- Method / resource A classification framework for model improvement strategies was proposed.
- Method / resource All strategies improved cropland evapotranspiration estimates to varying degrees.
- Method / resource Input mechanism enhancements produced the highest R2 gains.
- Method / resource RMSE% error reduction did not differ significantly among strategies.
- Association Improvement strategies influenced model accuracy more than environmental conditions.
- Association RMSE% retained notable room for optimization with different initial performance.
- Method / resource Current models have not attained optimal performance in cropland regions.
- Recommendation Future model development should reduce systematic bias and improve regional adaptability.
