Ecotech – Aurora 4000 Nephelometer

Aerosol Research

Category: Tag:


Aerosol particles in the atmosphere directly influence the earth’s radiative balance by absorbing and scattering the solar radiation and indirectly, by changing the cloud’s microphysical properties.

The phase function, defined as the amount of light scattered as a function of the scattering angle, is a key parameter to accurately model the influence of the aerosol scattering on the earth’s radiative balance. The Aurora 4000 provides integrated scattering measurements at a number of angles, assisting in the calculation of the phase function.

The Aurora 4000 is the first commercially available polar nephelometer in the world.
