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 consists of 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 s and measures hydrogen (H2), methane (CH4), and carbon monoxide (CO) every 140 s. The OZ sensor operates at 254 nm and provides ozone measurements every 10 seconds. The TDL spectrometer operates at 1370 nm and provides water vapor measurements every 1 s. UCATS was designed to be operated on UAS, but it has been deployed on piloted aircraft as well.
