- Airborne Chromatograph For Atmospheric Trace Species (ACATS) is designed to measure a variety of organic chlorine and long-lived species in the stratosphere and upper troposphere. The instrument includes four separate gas chromatographic (GC) channels each incorporating an electron capture detector. Channels can be configured by selecting different GC columns to measure the following combination of individual trace gas species: CFC-11 and CFC-113; CH3CCl3 (MC) and CCl4 (CT); CFC-12 and N2O; or HCFC-22, CH3Cl, or hydrogen, methane and carbon monoxide. The gas chromatograph can measure one sample every 2-3 minutes with a detection limit of 2% of the maximum tropospheric value. The absolute accuracy of the measurement is +/- 3% plus precision.
This research is supported by the High Speed Research Program (HSRP) of NASA and the Atmospheric Chemistry Project of NOAA's Global Climate Change Program.
