PREV ’AIR :
An operational system for large scale air quality monitoring and forecasting
www.prevair.org
Architecture of the PREV’AIR System
3D Chemistry Transport Models... CHIMERE / IPSL-CNRS-INERIS MOCAGE / METEO-France open system to other models...
… Driven by meteorological forecasts: AVN / NCEP global data (+ MM5 higher
resolution forecasts) ARPEGE, ALADIN
... Using input data: emissions inventory (EMEP) boundary conditions (MOZART) land-use (GLCF data base)
NRT observation data: BASTER/ADEME NRT database centralizes
data from 40 French local AQ monitoring networks
bilateral cooperation with other partners

Applications
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 …

Ozone, averaged peak (µg/m3) during summer 2003
Modelled concentrations corrected with near real time data:
Near real time data from 150 selected stations
Statistical adaptation using a kriging method
Available at J+0 with updates if near real time observations available
Feasibility study for the PM

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: [email protected])
for forecasts or analyzed maps: users accounts could be available to download over specific
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
AQ expertise for the Ministry
Model development CHIMERE aerosol
ADEME National Agency of EnvironmentBuilds up and hosts the NRT database
