The Airborne Cavity Enhanced Spectrometer (ACES) is a two-channel spectrometer designed for aircraft measurements of glyoxal (CHOCHO), methylglyoxal (CH3COCHO), nitrous acid (HONO), nitrogen dioxide (NO2), and water vapor (H2O). ACES makes high-sensitivity measurements of trace gases and aerosols as light passes through the optical cavity equipped with a grating spectrometer and a charge-coupled device. ACES operates across two wavelength ranges (361-389 nm and 438-468 nm) and has high precision and temporal frequency.
