A dataset of remote sensing-based inherent optical properties of Hulun Lake from 2016 to 2020
摘要
Abstract
Hulun Lake,the largest steppe lake in the high latitude semi-arid region of inland China,holds great significance for grassland production and steppe-lake ecosystem.The absorption coefficient of water constitutes is indicative of the optically active components in water,thus conducive to estimating the optically active substances and other related bio-optical parameters of waters.In this study,we used the quasi-analytical algorithm(QAA),a QAA-750E absorption coefficient inversion algorithm suitable for inland waters.Based on Sentinel-3/OLCI remote sensing reflectance data,we produced a dataset of monthly mean phytoplankton absorption coefficient aph(675)and backscattering coefficient bbp(560)of Hulun Lake during 2016-2020.Validation analysis results show that the model-derived b_bp(560)has an R2 value of 0.59,RMSE of 0.55,and MRD of 0.54(N=15),indicating a high level of reliability of the dataset.The dataset is expected to offer data support for water quality monitoring and ecological environment protection of Hulun Lake.关键词
