NEPHELOMETER-AIR
3-Wavelength integrating nephelometer aboard aircraft
Baseline Instrument, 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%.
