AOS Dry Nephelometer 1 Minute Averages - aosnephdry1m

The nephelometer measures the total scattering and hemispheric backscattering of aerosol. Nephelometers are deployed in pairs, with one measuring the ambient conditions and the other measuring the scattering as a function of slowly increasing or decreasing relative humidity (RH). The combination can then be used to derive the hygroscopic growth factor as a function of RH: f(RH). \n \nThe nephelometer is part of the aerosol observing system (AOS).浊度计（Nephelometer）用于测量气溶胶的总散射与半球后向散射。该设备通常成对部署，一台用于监测环境大气条件，另一台用于测量随相对湿度（RH）缓慢升降时的散射特性。结合两组测量数据，可推导得到以相对湿度为变量的吸湿增长因子f(RH)。 浊度计是气溶胶观测系统（Aerosol Observing System, AOS）的组成部分。
