Measurements of Atmospheric Halons at NOAA/CMDL/HATS
Entry ID: NOAA_CMDL_NOAH_HALONS

[ Update this Record ]

Summary
Abstract: The National Oceanic and Atmospheric Administration's (NOAA) Climate
Monitoring and Diagnostics Laboratory (CMDL)/Halocarbons and other
Trace Species Group (HATS) is currently measuring halons in the
atmosphere. Measurements of Halon-1211 and -1301 are measured by
electron-capture gas chromatography (ECGC) and gas chromatography mass
spectrometry (GCMS). H-1301 (bromotrifluoromethane or CBrF3) is
detected by only ECGC while H-1211 (bromodichloromethane or CBrClF2)
is measured by both methods. Flask samples of air from the HATS
network are analyzed on a bi-monthly or monthly basis; other flasks
are collected on research cruises:

SAGA II (1989) and SAGA III (1990): Soviet/American Gas and Aerosol
RITS 89 (1989): Radiatively Important Trace Species
BLAST I (1994), BLAST II (1994), BLAST III (1996): Bromine Latitudinal
Air/Sea Transect
OAXTC (1992): Ocean/Atmosphere Exchange of Trace Compounds

Stations in the HATS network measuring halons are:
ALT: Alert, Northwest Territories, Canada
BRW: Point Barrow, Alaska, USA
NWR: Niwot Ridge, Colorado, USA
MLO: Mauna Loa, Hawaii, USA
SMO: Cape Matatula, American Samoa
CGO: Cape Grim, Tasmania, Australia
SPO: South Pole Station, USA

Principal investigators for the halon flask measurements are:
J. Butler, S. Montzka, and J. Elkins (NOAA/CMDL)

The NOAA/CMDL data are available via anonymous ftp as follows:
