In support of the Group on Earth Observations (GEO) objectives and as a space component of the Global Earth Observation System of Systems (GEOSS), CEOS has developed the concept of virtual space–based Constellations. The Constellation concept builds upon or serves to focus existing projects and activities and provides a means to maximize the value of existing space assets among partners. A goal of a Constellation is to demonstrate that added value can result through partnership among the space agencies and their supported institutions.<br>The Atmospheric Composition Constellation (ACC) focuses on observations needed for understanding and to improve predictive capabilities for changes in the ozone layer, climate forcing, and air quality. At the present time, ten space agencies are collaborating in ACC and have established three projects to demonstrate how added value can be obtained by combining satellite data sets. These initial projects are directed towards applications which focus on GEO Societal Benefit Areas (SBAs) including Air Qaulity. Human industrial activities including the combustion of fossil fuels, land–use and biomass burning, lead to the emission of gases and particles, which pollute the air. Once aloft, air pollution can travel long distances and as a result, it is a global problem.<br>Air Quality monitoring at urban and regional scale is typically performed using in–situ measurements and regional models. Space–borne measurements provide now global coverage complementing in–situ data.<br>The purpose of this ACC–Workshop is: <ul><li>to review the current accuracy of space based tropospheric measurements (in particular sulphur dioxide, nitrogen dioxide, carbon monoxide, ozone and particulate matter) </li><li>to see if existing satellite measurements are already able to provide value–adding information to air quality monitoring in addition to in–situ data </li><li>to review the need of future space based air quality monitoring missions.</li></ul>This workshop will be organised around oral presentations of experts in atmospheric satellite retrieval and data assimilation (combining ground–based and satellite measurements), and end –users, who monitor on regular basis air quality. The workshop outcomes and recommendations will be reported to the CEOS agencies.
