The observation sites are located at Zhangye National Climatological Observatory, Semi-Arid Climate and Environment Observatory of Lanzhou University （SACOL）, and Jingtai with the Mobile Facilities of SACOL. The measurements of Particle Soot Absorp- tion Photometer and TSI Integrating Nephelometer are used to analyze the aerosol absorption and scattering characteristics over Zhangye. The results are： the aerosol absorption, total scattering, and backscattering coefficients present similar diurnal variation trends with their bi-peaks at 08：00 and 22!00, and they are generally higher in nighttime than in daytime. Their monthly average coefficient is the highest in April, and the!l drops in succession in May and June. Frequency analysis of aerosol single scattering albedo （SSA） shows that the magnitudes＇0f SSA at 450, 550, and 700 nm are mainly within 0.7q3.9. The maximum frequency of SSA at 450 and 700 nm distribute at 0.8, and at 0.85 for 550 nm. The averages of SSA at 450, 550, and 700 nm are 0.72, 0.75, and 0.68, respectively.展开更多
