Abstract :
In this paper, we compared the aerosol optical properties (single scattering albedo(SSA), real part part of refractive index(mr)) at 0.44 μm retrieved from two different (principal plane(PP) and almucantar(ALM)) measurement of sky radiance, which observed from ground-based sun-sky radiometer CE318. We found 75% cases of SSA and mr retrieval are higher retrieved from ALM compared with PP, and SSA has a high correlation (R2=0.848) between these two measurement, while mr has a low(R2=0.019).
