Uncrewed Aircraft Systems (UAS) Chromatograph for Atmospheric Trace Species
The Uncrewed Aircraft Systems (UAS) Chromatograph for Atmospheric Trace Species (UCATS) is an in situ airborne instrument suite that measures trace gases in the atmosphere. It includes three separate instruments: a three-channel gas chromatograph (GC), a dual-beam ozone photometer (OZ), and a tunable diode laser (TDL) spectrometer. The GC measures nitrous oxide (N2O) and sulfur hexafluoride (SF6) every 70 seconds and detects hydrogen (H2), methane (CH4), and carbon monoxide (CO) every 140 seconds. The OZ sensor operates at 254 nm and provides ozone measurements every 10 seconds. The TDL spectrometer operates at 1370 nm and offers water vapor measurements every 1 second. UCATS was designed for operation on UAS, but it has also been deployed on piloted aircraft.
