全球湖泊项目是一个湖泊对环境变化响应的全球观测站，旨在利用当前的卫星任务和长期遥感档案对多个湖泊生态系统进行天气性研究，评估其当前状况，重建过去的系统轨迹趋势，并评估湖泊对多种变化驱动因素的敏感性。本文介绍了基于遥感技术和全球湖泊和湿地数据库中列出的世界上最大的3721个湖泊和水库的初始池，将湖泊纳入全球观测站的选择协议。一份长达18年的卫星数据档案被用于创建空间和时间过滤器，以确定适合遥感方法的水体。采用和测试进一步的标准，以确保候选地点涵盖广泛的生态环境和特征；总共960个湖泊、泻湖和水库被选中。本文提出的方法适用于新一代卫星，如欧洲空间局哨兵系列卫星。
The GloboLakes project, a global observatory of lake responses to environmental change, aims to exploit current satellite missions and long remote-sensing archives to synoptically study multiple lake ecosystems, assess their current condition, reconstruct past trends to system trajectories, and assess lake sensitivity to multiple drivers of change. Here we describe the selection protocol for including lakes in the global observatory based upon remote-sensing techniques and an initial pool of the largest 3721 lakes and reservoirs in the world, as listed in the Global Lakes and Wetlands Database. An 18-year-long archive of satellite data was used to create spatial and temporal filters for the identification of waterbodies that are appropriate for remote-sensing methods. Further criteria were applied and tested to ensure the candidate sites span a wide range of ecological settings and characteristics; a total 960 lakes, lagoons, and reservoirs were selected. The methodology proposed here is applicable to new generation satellites, such as the European Space Agency Sentinel-series.
