The research project aims to use tractor based canopy temperature measurements in conjunction with micrometeorological measurements as an operational tool for characterising soil water characteristics site specifically in agricultural fields. This will be done using a simulation modelling and model inversion approach. A crop growth model shall then be used to calculate winter wheat yield potentials site specifically. For this purpose specific experiments on a plot scale in a rain out shelter and at the field level are planned to supplement existing extensive experimental data set for further model refinement. Special emphasis will be given on establishing stomata resistance functions and on problems of infrared based measurements of canopy temperature in sparse canopies.

该研究项目的目的是将基于拖拉机的顶篷温度测量与微气象测量结合使用，作为一种专门在农业领域的土壤水特征地点的操作工具。这将使用仿真建模和模型反转方法完成。然后，应使用农作物生长模型来计算冬小麦产量的特定位点。为此，计划在雨水庇护所和现场层面上进行绘图量表进行特定的实验，以补充现有的广泛实验数据集，以进行进一步的模型改进。将特别重点放在建立气孔抗性函数和稀疏檐篷中基于红外的冠层温度的问题上。
