2026-08-12 Northeast China 10-meter resolution lake CDOM dataset (2020) doi:10.57760/sciencedb.iga.01502 en a. Data content (data file/table name, including observation indicator content) This dataset utilizes Sentinel-2 imagery and a lake CDOM field dataset from research institutions to construct a CDOM inversion model for eight typical lakes (including reservoirs) in Northeast China. It produces a Northeast China lake CDOM dataset for 2020, reflecting the distribution of CDOM in Northeast China's lakes in that year. The dataset includes one tif file and eight shapefile files, providing both raster and vector data for the lakes. b. Construction purpose Conduct a quantitative study on the distribution characteristics of CDOM in Northeast China's lakes in 2020, establish a spatial distribution database of CDOM in Northeast China's lakes, and provide data support for the sustainable development of water resources in Northeast China's lakes. c. Service recipients It can be widely applied to managers of lakes, reservoirs, watersheds, and environmental departments, as well as students and researchers engaged in lake hydrological studies. d. Time range of data 2020 e. Spatial scope of data Eight typical lakes in Northeast China f. Data projection method Geographic Coordinate System：GCS_WGS_1984 g. Disciplinary scope of data Belonging to the scope of water environment remote sensing h. Amount of data The total data volume is approximately 800 M Northeast China; lake CDOM; 2020 Shang Ying-xin PUBLIC https://creativecommons.org/licenses/by/4.0/ dataset Science Data Bank
