The Aerosol Optical Properties (AOP) is an in situ airborne suite consisting of a Cavity Ringdown Spectrometer (CRDS), Photoacoustic Absorption Spectrometer (PAS), and Ultra-High Sensitivity Aerosol Size Spectrometer (UHSAS). It provides multi-wavelength measurements of aerosol extinction, absorption, and other properties. CRDS measures aerosol extinction at 405, 532, and 662 nm wavelength and has an accuracy of less than 2%. PAS measures absorption at 405, 532, and 660 nm wavelengths and has a sampling rate of 1 Hz. UHSAS measures the size distribution of aerosol particles within the size range of 0.008 to 1 μm. The measurements from the combined AOP instrument package allow for the calculation of radiative forcing and atmospheric heating rates.
