Ames Extinction Scattering Optical Property Instrument (AESOP)

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.

Measurements: 
Particle Extinction, Single Scattering Albedo
Aircraft: 
Twin Otter - GRC
Point(s) of Contact: 
Anthony Strawa (POC; PI), Rudolf Pueschel (PI)
