2023-12-18 A dataset of water clarity of Hulun Lake from 2000 to 2019 doi:10.57760/sciencedb.07663 en Water clarity is a significant parameter to evaluate the water quality of lakes. Monitoring the long-term temporal and spatial changes of water clarity of lakes can provides references for evaluating the water quality and eutrophication status of water bodies, and lake environmental management as well as ecological restoration. With MODIS Terra satellite image, we excluded the influence of cloud cover and other interference factors and estimated the water clarity (Secchi disk depth), and finally generated time series data of the water clarity of Hulun Lake from 2000 to 2019. After verification, the data have a high accuracy, meeting the requirements of monitoring. This data set is expected to provide data support for remote sensing monitoring of water quality and environmental governance of Hulun Lake in a long time series scale.
