INERIS in brief

3

➢ INERIS is a member of the Central Laboratory for Air Quality Monitoring (AQM) in charge of:

▪ the coordination of the air quality monitoring strategy in France, ▪ support the Ministry of the Environment for decision making, negotiations of the regulations and communication, ▪ coordination and support of local organizations (AASQA) in charge of AQM

➢ INERIS supports French authorities for the implementation of air quality management strategies and negotiation of international legislations (e.g. European AQ Directives or protocols of the UN Convention on Long Range transboundary air pollution) ➢ INERIS develops the French national air quality model with the national scientific center (CNRS) for forecasting and scenario analysis

INERIS, the reference organisation for Air Quality at national and European Levels

Use of models to complete the monitoring strategy The CHIMERE model (partly developed by INERIS)

Strengths: Easy to implement, free Useable in the world State of the art model Works on HPC or linux cluster

5

International experience

International expertise in Air Quality Management ➢ European Copernicus services for EU authorities: environmental monitoring services implementation

▪ INERIS is a leader of COPERNICUS services related to policy support and a key player of the COPERNICUS forecasting platform

➢ Chair of the EMEP program supporting the UN Convention on Long-range Transboundary Air Pollution (Laurence Rouïl) ➢ INERIS as a partner of the European Topic Centre for Air Pollution and Climate Change Mitigation for the European Environmental Agency ➢ Close cooperation with international institutions like EU JRC, IIASA, ECMWF ➢ INERIS works for customers worldwide in Senegal, Chile, Tunisia (via Aria) and China (BMILP)

The french air quality forecasting system PRE’VAIR (www.prevair.org)

➢ An operational system that has become a part of the French air quality monitoring strategy. ➢ A new approach, borne by numerical tools, to reinforce the air quality management network, with new products :

▪ Forecasts: since 2003, public information procedures and emergency measures are based not only on measurements but also on forecasts.

• Regulatory pollutants: O3, NO2 and PM
• Global / European / French scales
• 3 days ahead  Prevention of exposure

Use of observational data in PREV’AIR

Use of statistical data to improve the raw simulations

From the regional scale …

10

➢ Use of different types of models to asses the local impact of industrial plants ➢ Chronic release ▪ Mapping of mean concentration and deposition of pollutant over period of 3-5 years. ▪ Estimation and localization of the maximum impacted area ➢ Accidental release ▪ Find the maximum concentration an fallout

• f pollutants

▪ Calculate the Effective Dose computation

…to the local scale

Case of the Icelandic volcano eruption in April 2010

➢ Evaluation of the consequences on air quality in France

In-situ observations of the plume around Paris Use of models to track the pollution plume

Simulation at the global scale (anthropic PM2.5) March 5th-18th, 2014

13

Impact of dust emissions on air quality

14

➢ Exemple: Evaluation of the impact of foreign emissions (in %) for PM10 ➢ Method: remove the national emissions in the model Assessment of the transboundary air pollution

15

Scenario analysis during episodes

Reduction effect on ammonium nitrate concentrations :

• 30% of french agricultural NH3

versus

• 30% of french traffic NOx

16

Scenario analysis for long term policies Evolution of PM10 concentrations according to the Directives on emissions

Evaluation of individual measures at the national scale to reduce air pollution

• Cost / benefices analysis (avoided cost on health)
• Impact on air quality

17

Air quality and Climate Change Suite of models

Cost benefit analysis of emission reduction measures ➢ Integrating Air Pollution policy in Climate policy in policy brings additional benefits in terms of GHG reductions, at negligible cost ➢ Additional costs for the energy system are almost offset by Additional benefits in terms of reduced AP mitigation costs, and by additional health benefits ➢ Measures can be tested independently

Synergies between the partners

• Different status : private, public and research organisations
• Different products : stations, models, lidars
• Different expertises : network design, impact and cost

assesments, health impacts and public exposure (indoor,

• utdoor), advising authorities, public information …

for integrated or tailor made solutions

22

➢ Expertise on air quality management including modelling (and also emission and ambient measurements) ➢ Air quality forecasting (local, regional and global scale) – Impact of industrial facilities (on line forecasting of industrial plants ➢ Scenario analysis – cost benefit analysis of mtigation measures ➢ Assessment of the transboundary pollution ➢ Air quality & Climate change ➢ Integrated views from emissions to health impacts (Health risk assesment studies)
