Abstract OK) and Inverse Distance Weighting (IDW). The modeling accuracy varies between 2.14 days and 11.45 days for heading and emergence of winter wheat, respectively. The uncertainty of the majority of the modeled phases is less than a week. The model is universally applicable due to automatic parametrization, but model accuracies depend on the crop type and increase during a growing season. The possibility to enhance the model by additional explaining variables is demonstrated by consideration of soil moisture within an extended model setting.
