Global Emissions Inventory Activity, International Global Atmospheric Chemistry, International Geosphere-Biosphere Program

Service Provider Description
The Global Emissions Inventory Activity (GEIA) was created in
1990 to develop and distribute global emissions inventories of
gases and aerosols emitted into the atmosphere from natural and
anthropogenic (human-caused) sources. The long-term goal is to
develop inventories of all trace species that are involved in
global atmospheric chemistry.

GEIA's mission is to provide high quality data and information
for timely, relevant assessments. The requirements for a data
set to be accepted as a GEIA data base include substantial peer
review as reflected by acceptance for journal publication and
agreement among the individual GEIA project teams.

To ensure that the best available data can be easily accessed by
users, GEIA provides links to "pre-GEIA" data for projects that
do not yet have a formal GEIA data base and projects where the
formal GEIA data need to be updated. These interim pre-GEIA data
and data requiring updates have not yet undergone the formal
GEIA review requirements. To enhance development and
distribution of the highest quality information, GEIA also
facilitates communication with other related data base and
assessment activities by providing links to these activities.

GEIA's mission will be expanding to be more responsive to the
needs of the global research and assessment community as a
result of the 2003 planning.
