1. First results and simulations plan with CHIMERE for NATAIR (WP5) Gabriele Curci, LISA Matthias Beekman, LISA, CNRS Robert Vautard, LSCE/IPSL, CNRS NATAIR Project Meeting, 23-24 October 2006, Oxford, UK

2. NATAIR meeting 3 June 2015, Oxford Gabriele Curci, LISA - CHIMERE Simulations2 of 14 Objectives of WP5 Estimation of fraction of atmospheric pollutants over Europe which can be attributed to natural/biogenic emissions: → Incompressible part of air quality Calculations rely on CHIMERE chemistry-transport model with updated biogenic emissions from NATAIR project Some specific objectives: Document the improvement of updated biogenic emission inventory Determine “natural vs antro” share of primary and secondary pollutants Interaction between anthropogenic and biogenic emissions: For given bio emissions how changes in anthro emissions affect air quality? Could bio emissions reduce effectiveness of European AQ management? Biogenic emissions and climate change (qualitative)

NATAIR meeting 3 June 2015, Oxford Gabriele Curci, LISA - CHIMERE Simulations14 of 14 Data needs – Cadastre Option General needs : Domain: Natair domain is fine Horizontal resolution: 10*10 km is fine, we will make simulations at 0.5° Temporal resolution: 1h Years: 1997, 2000, 2001, 2003 WARNING: is we don’t receive the emissions for all these years we cannot perform all the planned simulations Data should be ASCII or Binary netcdf or else binary NOT GIS dependent Please provide us with a sample of the data we will have later to prepare interfaces * Auxiliary data in same format may be helpful for interpretation, i.e. landuse, meteo parameters curci@lisa.univ-paris12.fr
