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

<em>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.</em>水体透明度以赛氏盘透明度（Secchi disk depth, Zsd）为表征指标，是水质的一级指示指标。本数据集涵盖中国华东地区86个面积大于30平方千米的主要大型湖泊的赛氏盘透明度数据，所有数据均通过基于随机森林回归（random forest regression, RFR）的赛氏盘透明度估算模型估算得到。从事光学遥感与水生科学研究的科研人员可将本数据集应用于其相关研究工作。
