Instrument : Nephelometer (NEPHELOMETER)

Instrument Categories
Aerosols

A nephelometer measures the total scattering and hemispheric backscattering of aerosol. Nephelometers are deployed in pairs with one of them measuring the ambient conditions and the other measuring the scattering as a function of slowly increasing or decreasing relative humidity. The combination can then be used to derive the hygroscopic growth factor as a function of RH: f(RH).

The NEPHELOMETER is part of the Aerosol Observing System (AOS).

Output Datastreams

  • aosnephdry : AOS: ambient nephelometer measurements
  • aosnephwet : AOS: humidified nephelometer measurements
