The
Halocarbons and other Atmospheric Trace Species (HATS) group of NOAA/GMD has
designed and built three instruments since 1991 for implementation onaircraft
and/or balloon platforms. Each instrument is a multi-channel gas
chromatograph (GC) that measures halogenated trace gases (e.g., chlorofluorocarbons and halons)
and other important atmospheric tracers. All of the HATS airborne instruments
make measurements using gas chromatography with electron capture detectors
(ECDs).
The data obtained from these instruments permit studies of chemistry
and transport in the upper atmosphere.
Airborne Instruments and years of operation
- ACATS-II — two
channel GC for ER-2 platform (1989-1992)
- ACATS-IV — four
channel GC for ER-2 platform (1993-2000)
- LACE — three
channel GC for high-altitude balloons and WB-57 platforms (1995-2004)
- PANTHER — six
channel GC with ECDs and a mass selective detector (MSD) for WB-57,
DC-8, and Gulfstream-V aircraft (2000-Current)
- UCATS — two
channel GC with ozone and water vapor instruments for Altair UAS and
Gulfstream-V aircraft (2004-Current)
NASA Campaigns and Projects
Data can be found for all of these missions on the NASA
ESPO Data Archive web site. The aircraft data uses the prefix "GC",
"MSD" and "BC".
