GEOmon
This 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.

WP 1.2 CARIBIC Flying laboratory
Measurement 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)
Activity 2: Atmospheric Aerosols and Climate
Activity 4: Stratospheric Ozone and Climate
Activity 5: Integration and Supporting Modelling Studies
Activity 6: System Architecture and Outreach
• Global change
detection
• Assessment of
the atmospheric
state
• Information for
policy makers
and the general
public
 Deploy new ground-based remote sensing stations for satellite groundtruthing
 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)
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?
