nephelometer-air > 3-Wavelength integrating nephelometer aboard aircraftInstrument Type(s) > Baseline • Guest

The integrating nephelometer measures aerosol particle optical scattering coefficients (total scatter and backscatter) by detecting the light scattered by aerosol for three wavelengths: 700, 550, and 450 nm. Onboard the aircraft, the nephelometer samples directly from the isokinetic manifold, with a designated heater mounted upstream to control the relative humidity at or below 40%.
