Chlorophyll-a is an important indicator of lake water quality: Based on the in-situ information collection in Boyang Lake, one of the biggest lakes of China, from 2009-2012, including water body spectral information, the spectral index was constructed based on the water spectral characteristics analysis. Integrating the data and the least squares method to analyze the relationship between the spectral data and the Chlorophyll-a, the concentration of the Chlorophyll-a was conducted in January, April, July and October from 2009 to 2012. The data of Chlorophyll-a indicates that the most lowest months are December to February, the Chlorophyll-a increased from March to July, and reach the peak of the year in July; after August, the Chlorophyll-a decreased, and reach the lowest by end of the year. The spatial distribution shows that more close to the beach, more high of the Chlorophyll-a. The data is archived in two data files, one in .tiff format and one in .xls format.
