Abstract Haze pollution es more and more frequent in urban regions of China. Compared to ground based measurement ap-

CCD blue and green bands based on the assumption of stable surface reflectance in a short period. Applications of HJ-D haze
monitoring are also evaluated and feasibility and advantages of the high-resolution satellite are analyzed.
