Advanced
Global Atmospheric Gases Experiment (AGAGE), and its
predecessors (the Atmospheric Life Experiment, ALE, and the Global
Atmospheric Gases Experiment, GAGE) have been measuring the
composition of the global atmosphere continuously since 1978. The AGAGE
is distinguished by its capability to measure over the globe at high frequency
almost all of the important gases species in the Montreal Protocol (e.g. CFCs
and HCFCs) to protect the
ozone layer and almost all of the significant non-CO2 gases in the Kyoto Protocol
(e.g. HFCs, methane, and nitrous oxide) to
mitigate climate change. |

AGAGE is part of the powerful global observing system that is measuring
halocarbons, including bromocarbons, in the Earth's atmosphere. The ALE/GAGE/AGAGE stations
occupy coastal sites around the world chosen to provide accurate
measurements of trace gases whose lifetimes are long compared to global
atmospheric circulation times.
AGAGE also collaborates with the System
for Observation of Halogenated Greenhouse Gases in Europe (SOGE),
through transfer of AGAGE calibrations and sharing of AGAGE technology, placing
AGAGE and SOGE data on common calibration scales with comparable
precisions, accuracy and measurement frequency. AGAGE's network also
includes Hateruma Island, Japan through a co-operative agreement with the
Japanese National Institute for Environmental Studies (NIES).
A station at Gosan, Jeju Islan, Korea to be operated by Seoul National
University is planned.
