大气浑浊度（atmospheric turbidity）是指无云大气铅直气柱中气溶胶散射造成的消光程度。铅直气柱中气溶胶含量越大，大气浑浊度也越大。大气浑浊度的研究对太阳辐射传输，气侯变化. 大气环境保护等都有重要意义。
结果表明：阿贡山和随后的几个火山爆发导致了1963年秋季以后大气浑浊度的普遍增加，特别是在秋冬季节。
It is found that Agung's and several other volcanic eruptions have increased the atmospheric turbidity after the autumn of 1963, especially during the autumn and winter seasons.
最后给出了北京地区地面太阳紫外总辐射的变化趋势，计算结果表明，地面太阳紫外总辐射对大气浑浊度的变化比对大气臭氧总量的变化敏感得多。
The calculation results show that the ultraviolet radiation received at the ground is more sensitive to changes in atmospheric turbidity than changes in the total ozone amount.
利用积分浑浊度仪监测得到的散射系数和多波段光度计观测资料分析了兰州冬季大气气溶胶的一个个例的散射光学特征。
The scattering optical characteristics of aerosol over Lanzhou in winter are analyzed, using the data monitored by Integrating Nephelometer and Multi-wavelength Sun-photometer.
