META-DATA for IEA Wind Task 46. WP2: Atmospheric drivers of wind turbine blade leading edge erosion: Ancillary variables

Leading edge erosion (LEE) of wind turbine blades has been identified as a major factor in decreased wind turbine blade lifetimes and energy output over time. Accordingly, the International Energy Agency Wind Technology Collaboration Programme (IEA Wind TCP) created Task 46 to undertake cooperative research in the key topic of blade erosion. This report is a product of WorkPackage 2 <strong>Climatic conditions driving blade erosion. </strong> The objectives of the work summarized in this report are to: Summarize efforts to elucidate critical atmospheric co-stressors that may accelerate leading edge erosion and hence for which meta-data regarding observations should be collated. Briefly describe and summarize additional data pertaining to those LEE co-stressors from sites that were the focus of analyses of hydrometeors in the report “Atmospheric drivers of wind turbine blade leading edge erosion: Hydrometeors” (Pryor et al. 2021) Accompanying this report is a detailed spreadsheet that summarizes the meta-data regarding these co-stressor variables.风力机叶片前缘侵蚀（Leading Edge Erosion, LEE）已被证实是导致风力机叶片服役寿命缩短、长期发电输出下降的关键因素。为此，国际能源署风能技术合作计划（International Energy Agency Wind Technology Collaboration Programme, IEA Wind TCP）设立任务46，围绕叶片侵蚀这一核心主题开展协同研究。本报告为工作包2——**驱动叶片侵蚀的气候条件**——的研究成果。本报告所总结的研究目标如下：1. 梳理阐明可能加速前缘侵蚀的关键大气协同应力因子的相关研究工作，并整理针对这些因子的观测元数据；2. 简要描述并总结来自《风力机叶片前缘侵蚀的大气驱动因子：水凝物》（Pryor等，2021）报告中作为水凝物分析重点站点的相关LEE协同应力因子的附加数据。本报告附带一份详细的电子表格，汇总了上述协同应力因子变量的元数据。
