Results of OLCI-derived Secchi disk depth in lakes across East China

Water clarity, represented by Secchi disk depth (Zsd), is the first-order indicator of water quality. This dataset contains Zsd of 86 major large lakes with an area greater than 30 km2 in East China estimated using a random forest regression (RFR)-based Zsd model. Scientists from optical remote sensing and aquatic sciences can use this dataset for their research

水体透明度以赛氏盘深度（Secchi disk depth, Zsd）为表征，是水质的一级指示指标。本数据集涵盖中国东部86个面积大于30平方千米的主要大型湖泊的赛氏盘深度数据，所有数据均基于随机森林回归（Random Forest Regression, RFR）模型估算得到。光学遥感与水生科学领域的科研人员可利用本数据集开展相关研究工作。
