2000-2020年全球500 m大型湖泊FUI水色指数逐月遥感产品

基于MODIS卫星遥感数据，发展了遥感数据预处理方法与湖泊FUI水色指数遥感提取算法，构建了2000-2020年全球1000余个大型湖泊FUI水色指数长时间序列遥感产品数据集。该数据集将为近20余年全球湖泊水色和水质时空变化规律研究提供科学数据支撑，并将在进一步的全球湖泊水色变化与水文要素、气候变化以及人类活动之间的相互作用响应机制研究中发挥重要作用。

Based on MODIS satellite remote sensing data, remote sensing data preprocessing methods and the remote sensing extraction algorithm for the lake FUI water color index were developed. A long-term time-series remote sensing product dataset of FUI water color indices for over 1,000 large lakes worldwide spanning 2000 to 2020 was thus constructed. This dataset will provide scientific data support for research on the spatiotemporal variation patterns of global lake water color and water quality over the past two decades, and will play a critical role in further studies investigating the response mechanisms of the interactions between global lake water color changes, hydrological factors, climate change, and human activities.
