The Carbon monOxide Measurement from Ames (COMA) is an in situ airborne spectrometer that measures carbon monoxide (CO) and nitrous oxide (N2O). It is an Off-Axis Integrated Cavity Output Spectrometer (OA-ICOS) manufactured by Los Gatos Research that has been converted for high-altitude (18 km) observations of CO and N2O. It has an uncertainty of 4.1 to 5.9 ppb for CO measurements and 2.7 ppb for N2O measurements. COMA has a typical measurement rate of 1 Hz.
