2026-08-12 Dataset of Chlorophyll-a Concentration Distribution in Lakes in Northeast China (2020) doi:10.57760/sciencedb.iga.01503 en a. Data content (data file/table name, including the content of observation indicators) This dataset utilizes Sentinel-MSI imagery and a measured dataset of lake chlorophyll-a to construct a global lake (including reservoir) chlorophyll-a inversion model, and produces a dataset of lake chlorophyll-a in Northeast China for 2020, reflecting the distribution of lake and reservoir chlorophyll-a in Northeast China in 2020. It includes one shapefile file, which is vector data. b. Construction purpose Conduct a quantitative study on the distribution characteristics of chlorophyll-a in lakes and reservoirs in Northeast China in 2020, establish a spatial distribution database of chlorophyll-a in lakes and reservoirs in Northeast China, and provide data support for the sustainable development of lake water resources. c. Service recipients It can be widely applied to managers of lakes, reservoirs, river basins, 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 Lakes in Northeast China with an area greater than 1 hectare 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 43.6 GB Northeast China; Chlorophyll-a Concentration Di; 2020 PUBLIC https://creativecommons.org/licenses/by/4.0/ dataset Science Data Bank
