The Airborne Carbonic Oxides and Sulfide Spectrometer (ACOS) is an in situ airborne spectrometer operated by NOAA. It is a modified Los Gatos Research (LGR) Off-Axis Integrated Cavity Output Spectrometer (OA-ICOS) used to measure carbonyl sulfide (OCS), carbon dioxide (CO2), carbon monoxide (CO), and atmospheric water vapor. ACOS provides these measurements simultaneously at a typical measurement rate of 1 Hz.
