4 AIRES : a regional operational air quality system from ESCOMPTE Workshop - 21,22 March 2005 Ecole Polytechnique, Palaiseau France AIRES (Atmospheric Integrated REgional System) : Air quality forecast and simulation system in PACA region (Provence Alpes Côte d’Azur). Daily 3D forecasts of ozone, nitrogen oxides, aerosols and others pollutants. based on CHIMERE and MM5 models (www.mmm.ucar.edu/mm5/). based on CHIMERE and MM5 models (www.mmm.ucar.edu/mm5/).www.mmm.ucar.edu/mm5/ Chemical boundary conditions : from PREV’AIR (www.prevair.org). Chemical boundary conditions : from PREV’AIR (www.prevair.org).www.prevair.org AIRES provides fine resolution forecasts at 12h, 24h and 48h over 3 different areas (ESCOMPTE, NICE and whole PACA).

This information is taken into account for regional regulation information. Upgreadeable et modular (links with IPSL, LISA, ACRI-ST) Upgreadeable et modular (links with IPSL, LISA, ACRI-ST) In the near future: AIRES will be involved in the PRIMEQUAL SCENARIOS PROGRAM. It will be able to evaluate the different impacts of reductions emissions scenarios. (I. COLL and F. LASRY – LISA) 16h20 today ! CONCLUSION

25 AIRES : a regional operational air quality system from ESCOMPTE Workshop - 21,22 March 2005 Ecole Polytechnique, Palaiseau France We are looking for tracks : forecast improvements in PACA region Does-it possible to start earlier D-1 computation ? Spin-up pb. For the first hours ? Does-it possible to start earlier D-1 computation ? Spin-up pb. For the first hours ? CHIMERE DUST version ?CHIMERE DUST version ? - Users returns ? - specials needs (inventory) ? - specials needs (inventory) ? - computer time versus « CHIMERE GAS version » - parallel version ? Exchange with others CHIMERE’s users Exchange with others CHIMERE’s users Specially with people who are faced with Breazes Phenomena - Pond Breaze - Sea Breaze - Valley Breaze QUESTIONS
