海洋环流与气候环境系列学术讲座(201904) 报告题目:Assessment of biogeochemical models: a four-level evaluation framework applied to the eReefs model for the Great Barrier Reef 报告摘要:The Great Barrier Reef is a World Heritage environmental asset of unparalleled natural value. The eReefs marine models have been developed to help guide policy and management of the Great Barrier Reef in a context of rapid decline due to multiple stressors, including climate change. The models are increasingly being relied upon to support a wide range of scientific and policy applications. It is therefore important to thoroughly document and characterise the performance of the model. In this short seminar, I will discuss a four-level model evaluation framework, considering (Level 0) sanity checks and accordance with known ecosystem function; (Level 1) traditional state variable evaluation metrics, including Willott skill assessment against monitoring data; (Level 2) assessment of a biogeochemical process rate, nitrogen fixation; and (Level 3) assessment of emergent properties and system-scale patterns such as phytoplankton community structure. This multifaceted approach is useful in highlighting strengths and weaknesses of the model and provides broader insight into model performance than traditional assessment against water quality monitoring time series alone. The four-level assessment approach may have broad applicability to complex, process-based environmental models. 报告人:Dr. Barbara Robson 报告人简介:Dr. Barbara Robson is a Principal Research Scientist at the Australian Institute of Marine Science and has more than 20 years of experience in biogeochemical modelling of estuaries and coastal ecosystems. She has a particular interest in models to support policy for the Great Barrier Reef, and in improving best practice in biogeochemical modelling. Dr. Robson is a Fellow of the International Environmental Modelling Society, an Associate Editor of the journal, Environmental Modelling & Software, and an Associate Editor of Limnology & Oceanography Letters. 报告时间:2019年2月27日(周三)上午9:30 报告地点:5号楼511会议室 欢迎各位老师和研究生参加! |
