Ecotech Aurora 3000
3 WAVELENGTH 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 clouds microphysical properties.
The amount of sunlight reaching the earth’s surface rather than scattered back to space, is an important parameter to accurately model the influence of aerosol scattering on the earth’s radiative balance. The Aurora 3000 provides this measurement by reporting both the integrated and backscattered coefficient.
Using a LED light source, the Aurora 3000 simultaneously measures at 525nm (green), 450nm (blue) and 635nm (red) to enable wide and in-depth analysis of the interaction between light and aerosols.
The ECOTECH Aurora 3000 includes backscatter measurements that allows both standard integrating measurements of 9-170° and also the backscatter 90-170°.
Selected materials available in other languages by request.
