Ames Extinction Scattering Optical Property Instrument

Status

Status
Operational
Operated By
PI

The Ames' Extinction Scattering Optical Property (AESOP) instrument measures aerosol extinction coefficient using cavity ring-down technology and scattering coefficient using reciprocal nephelometry. Measurements are made at two wavelengths (675 nm and 405 nm) with sufficient accuracy to obtain aerosol absorption coefficient, single scattering albedo, and the three Ångström exponents.
