PREV’AIR outputs: daily forecasts
O3, peak forecast (µg/m3)
20040729 D+0
 available at D+0, 00 h LT on the web site
 daily peak and averaged concentration maps
O3, peak forecast (µg/m3)
20040729 D+1
for D+0, D+1, D+2
 pollutants: O3, NO2 (France and Europe) and PM (Europe)
O3, peak forecast (µg/m3)
20040729 D+2
PREV’AIR outputs: scores (quality stats)
PREV’AIR outputs: numerical forecast data
PREV’AIR numerical data
 extraction over user-defined domains
 available through the Internet for AQ networks
(user accounts)
http://www.prevair.org/en/donneesnumeriques.php
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
PREV’AIR outputs: ozone analysis
immediately available for information (web sites, media…)
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

PREV’AIR outputs: maps near real time data
Maps of daily max and mean measured
concentrations :
 for O3, NO2, PM2.5 and PM10
 using observations made
between 0h and T time
 hour by hour updating if data
available (pollution events)
 for D day and the 6 previous days
Daily mean concentrations of PM10 at surface
measured on the 12 of September 2004
Towards an European framework...
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
www.prevair.org
Towards a 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

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:
INERIS
