Community Airborne Research Instrumentation (CARI)

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 NOy: Compact 2-channel chemiluminescence instrument / photolytic conversion / gold catalytic conversion (home built for GV).
  • NO, NO2, NOy, 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.
