In addition to satellite-based missions, GATS is involved in many airborne and ground based experiments to measure atmospheric trace gaseous and aerosol species related to jet exhaust, fires, global tropospheric chemistry, etc. For example, we participated in the International Crown Fire Modeling Experiment (ICFME) which measured trace gases and aerosols above forest fires using helicopter-based sampling equipment. Participants included representatives from:

• Canadian Forest Service (CFS)
• Government of the Northwest Territories (GNWT)
• United States Forest Service (USFS)
• National Aeronautics and Space Administration (NASA)
• National Center for Atmospheric Research (NCAR)
• National Institute of Standards and Technology (NIST)
• United States Geological Survey (USGS)
• Russian Academy of Sciences
• Commonwealth Society of Industrial Research Organizations (CSIRO) in Australia
• Max Planck Institute for Chemistry (MPIC) in Germany
• Universities in Canada, United States, Japan, Netherlands, and South Africa
