Overview

The CARI group is responsible for a number of aircraft trace gas instruments, including instruments that can be requested via the NSA/LAOF process, as well as others.

• CO: Two vacuum flourescence instruments (Aerolaser, one certified for GV).
• Picarro: A commercial cavity ring-down instrument for CH₄, CO₂ (certified for GV) .
• H₂O: Two TDL infrared absorption open-path water vapor instruments (MayComm Instruments, one certified for GV).
• Fast-O₃: Chemiluminescence instrument (home built for GV - HAIS).
• NO and either NO₂ or NO_y: Compact 2-channel chemiluminescence instrument / photolytic conversion / gold catalytic conversion (home built for GV).
• NO, NO₂, NO_y, O₃: 4-channel chemiluminescence instrument / photolytic conversion / gold catalytic conversion (home built for various aircraft, not certified for GV).
• PANs: Thermal Dissociation Chemical Ionization Mass Spectrometer (built in collaboration with Georgia Tech).
• NO, NO₂: A 1-channel instrument suitable for laboratory or other ground-based measurements.
