AQ information on public French channels (TV)

direct use for a local information (GIS)

input data for local modelling purposes :

ESMERALDA (Paris + 6 regions)

AERES (Marseille region), etc …

Involvement in the GMES program (Global Monitoring for Environment and Security) :

PROMOTE (ESA) = PROtocole MOniToring for the GMES service Element on

atmospheric composition (www.gse-promote.org)

Stage 1 (2004-5): demonstrator

Stage 2 (2006-8): develop air quality services related to forecasting and mapping;

define a cooperative framework with other European AQ teams

GEMS (EU) = Global and regional Earth-system (atmosphere) Monitoring using

satellite and in-situ data

contribution to the Air Quality part for the development of data assimilation methods and

ensemble forecasts

Towards an European framework...

=> Looking for bilateral cooperation with other European partners :

for NRT data exchange : necessary to build analyzed maps and to evaluate the simulated

results

(contact: nathalie.poisson@ademe.fr)

areas

ENDEND

Built for operational purposes:

In France public information related to pollution episodes (threshold exceedances) can be driven by observations but also by forecasts since 2003

The system : a cooperative system for large scale air quality monitoring, forecasting and

mapping over Western Europe and France ;

set up in 2003 by:

INERISPublic organization under the

supervision of the Ministry of Ecology

Builds up and hosts the prev ’air system
