  skos:definition """The Global Atmospheric Gases Experiment (GAGE) began in 1981,
continuing a global network program to provide continuous
high-frequency gas chromatographic measurements of methane (CH4);
nitrous oxide (N2O), Chloroflurocarbons CFCl3 (CFC-11), CF2Cl2
(CFC-12), and CF2ClCFC12 (CFC-113); methyl chloroform (CH3CCl3); and
carbon tetrachloride (CCl4).  The network includes observation
stations situated at different sites throughout the world: Cape Grim,
Tasmania; Point Matatula, American Samoa; Ragged Point, Barbados; and
Mace Head, Ireland; and Trinidad Head, California.  Stations existed
at Cape Meares, Oregon and Adrigole, Ireland. The GAGE is the second
phase of a monitoring network consisting of the Atmospheric Lifetime
Experiment (ALE) and the Advanced GAGE.  The GAGE phase began in 1981.
The ALE phase (1978-1986) utilized the Hewlett Packard HP5840 gas
chromotographs; the GAGE phase utilized the HP5880 gas chromotagraphs;
and the recently initiated Advanced Global Atmospheric Gases
Experiment (AGAGE) uses a new fully automated system from Scripps
Institution of Oceanography containing a custom-designed HP5890 and
Carle Instruments gas chromotographic components.
The ALE/GAGE/AGAGE daily and monthly data are available via anonymous
FTP from the Carbon Dioxide Information Analysis Center (CDIAC) as
follows:
ftp cdiac.esd.ornl.gov
cd pub/ale_gage_Agage/
or
"http://cdiac.esd.ornl.gov/ftp/ale_gage_Agage/"
The subdirectory, gage, contains data from the GAGE phase of the
experiment.
