Research on cyanobacteria blooms monitoring ability of HJ-1 CCD

Abstract

HJ-1 A satellite system consists of two optical CCD sensors, which can support real-time data for environmental monitoring because of their high temporal and spatial resolution, so that there is great potential in water quality monitoring for inland lakes. In this article, we analyze the ability for the monitoring of cyanobacteria blooms using 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 the same spatial and temporal resolution.
