HJ-1 satellite system consists of two optical CCD sensors, which can support real-time data for environment monitoring because of its high temporal and spatial resolution, so that there is great potential in water quality monitoring for inland lake. In this article, we analyze the ability of cyanobacteria blooms monitoring using the HJ-1 CCD data. First, the HJ-1 satellite is introduced and the potential ability in cyanobacteria blooms monitoring is discussed. Second, the HJ-1 CCD data and MODIS data are preprocessed and analyzed. Finally, the relative accuracy between the results of HJ-1 CCD and MODIS data are analyzed. The results indicate that the HJ-1 CCD data improve the cyanobacteria blooms monitoring ability in same spatial and temporal resolution.
