Polar Integrating Nephelometer

Aerosol particles in the atmosphere directly influence the Earth’s radiative balance by absorbing and scattering the solar radiation and indirectly, by changing the microphysical properties of clouds. Aurora 4000, the world’s first commercially available polar nephelometer, provides measurements of integrated light scattering between 10°- 90° and 180°, with the user able to select up to 18 separate angles between the 10° to 90° starting angle of the integration.
