My current research mainly focuses on the irrigation in land surface models, participating in the sub-project B05 ‘Towards a dynamic representation of irrigation in land surface models’ in the ‘CRC1502 Regional Climate Change: Disentangling the Role of Land Use and Water Management - 2022 to 2025’ project.
Our main task is to develop dynamic irrigation extent of Europe using process-based model simulation and remote sensing approach. We will better quantify differences in water use between dry and wet years by considering differences in the irrigated area and the irrigated crops in land surface models. The understanding of the dynamics in irrigation processes will be improved, and the comprehensively quantification human influences on water and energy flows will be carried out.
Previous work is mainly about the application of remote sensing in agriculture, including crop phenotyping using multi-source UAV remote sensing data; optimization of UAV monitoring schemes for crop growth, such as design optimal UAV sensor combinations and UAV flight mission schemes; diagnosis of environmental stresses of crop growth via the integration of UAV and satellite remote sensing.
