This project aims to develop, implement and evaluate a field monitoring technique building upon new theoretical developments to quantify evaporation and transpiration from soil and vegetation using a limited number of measurements of temperature, humidity and net radiation above soil and canopies. This new technique aims to characterise in situ the effect of vegetation cover on the partitioning of energy and water fluxes in areas with complex terrain and patchy vegetation. The project aims to produce new field experiment designs for optimal use of available technology and without restrictive limitations of fetch size required by traditional approaches (for example, eddy-covariance, Bowen ratio method).

该项目旨在开发、实施和评价一项实地监测技术，该技术建立在新的理论发展的基础上，通过对土壤和树冠上方的温度、湿度和净辐射进行有限数量的测量来量化土壤和植被的蒸发和蒸腾。这项新技术旨在现场表征在地形复杂和植被斑驳的地区植被覆盖对能量和水通量分配的影响。该项目旨在制定新的现场试验设计，以最大限度地利用现有技术，而不受传统方法(例如涡流协方差、鲍文比法)所需取样量的限制。
