GEOmonThis poster gives an overview of the latest results from the first year of the European 6th Framework project GEOmon (Global Earth Observation and Monitoring www.geomon.eu). The overall goal of the GEOmon project is to sustain and analyze European ground-based observations of atmospheric composition (complementary with satellite measurements) in order to quantify and understand ongoing changes. The project is a first step towards building an integrated pan-European Atmospheric Observing System for long-lived greenhouse gases, reactive gases, aerosols, and stratospheric ozone. GEOmon is a precursor of the GMES Atmospheric Service Insitu component and a European contribution to GEOSS.

Scientific Questions What are the regional European trends and variability of atmospheric

composition in relation to changes in surface emissions? How to validate and integrate satellite observations with ground-based and

airborne observations to obtain a coherent picture? What are the global trends of atmospheric composition, and how to reduce

the uncertainties of surface emissions and atmospheric processes?

Activity 1: Greenhouse gases and Global Warming Activity 2: Reactive Gases, Pollutants and Climate

Activity 2: Atmospheric Aerosols and Climate

Activity 5: Integration and Supporting Modelling Studies

Activity 4: Stratospheric Ozone and Climate

Activity 6: System Architecture and Outreach

Strategy

Deploy new ground-based remote sensing stations for satellite ground-truthing

Integrate ground-based, aircraft and satellite observations using advanced numerical transport-chemistry models

Build upon existing networks and improve their harmonization Establish the prototype of a pan-European atmospheric observing system of

greenhouse gases, reactive gases, aerosols, and stratospheric ozone Create a ‘One stop shop’ data centre for European atmospheric data Provide data storage and ongoing accessibility to data (past and present

projects)

The GEOmon project

The GEOmon project Integrated Project of the 6th European Commission Framework Programme 38 participating institutions, 4 years’ duration (started in February 2007) Coordination: P. Ciais, C. Textor, M. Logan (CEA-LSCE), P.Keckhut (CNRS-SA), France Contact: geomon.coord@lists.lsce.ipsl.fr, www.geomon.eu

GEOmon data centre

Surface observatories

WP1.1: In situ (17 sites) monitoring of CO2 and CH4 in the European boundary layer. Near real-time data now from several sites (e.g. Paris, London)

WP 1.2 CARIBIC Flying laboratoryMeasurement of ~100 species (trace gases, aerosol parameters) at 9-12 km altitude (UTLS), plus 2-4 profiles per flight (thus linking ground-based with satellite observations)

Measuring the modification of solar radiation by the atmosphere from the ground or with the earth surface (satellites)

WP 1.3 Measuring the modification of solar radiation by the atmosphere from the ground or with satellites: FTIR techniques.
