Background and Initial Partners
The Atmospheric Composition Constellation (ACC) and the Workgroup for Information Systems and Services (WGISS)
within the Committee on Earth Observation Satellites (CEOS) is developing a portal to support interoperability among the
atmospheric composition research and applications communities.
The portal was called for by CEOS as part of the sanctioned constellations and is a GEO task.
A need was perceived to develop a shared collaboration place for remotely sensed atmospheric composition related data and information.
This activity will be achieved through DLR's
International Council for Science ( ICSU )
/ World Meteorological Organization (WMO)
World Data Center for Remote Sensing of the Atmosphere (WDC-RSAT)
and NASA's Earth Science Data and Information Services.
The ICSU/WMO WDC-RSAT
is operated as a user service by DLR's
German Remote Sensing Data Center (DLR-DFD)
which offers scientists and the general public free access
to a continually expanding collection of satellite-based atmosphere-related
data sets, products and services. These data holdings range
from raw data collected by remote sensors, to information
products derived from the raw data ("value adding") and user-requested
In addition to archiving data sets and providing products
and services, ICSU/WMO WDC-RSAT cooperates with and establishes
links to other data centers and portals and connects users
to databases and portals that provide reliable, up-to-date,
integrated, and user-friendly information. WDC-RSAT thus forms
a contribution to the European Global Monitoring for Environment
and Security (GMES) initiative.
The Goddard Earth Sciences Data and Information Services Center (GES DISC)
is one of the Earth Science Data Center (ESDCs) ithin NASA's Earth Observing System Data
and Information System (EOSDIS). EOSDIS manages and distributes data products and services
from NASA's Earth system science data component of the Earth Science Division.
The ESDCs process, archive, document, and distribute data from NASA's past and current Earth system science research satellites and field programs.
The GES DISC is also part of
NASA's Global Change Data Center, which develops and operates data systems, generates science products, and provides archival and
distribution services for Earth science data in support of the U.S. Global Change Research Program
and NASA's Earth Science Program.
