2. LMDz-INCA General Description LMDz (Laboratoire de Météorologie Dynamique – Zoom); INCA (Interaction with Chemistry and Aerosols) Standard vertical resolution: 19 levels (surface to 35 km). Standard horizontal resolution: 96 long. X 72 lat. (3.75  X 2.5  ). Nudged with ECMWF met. Analyses – August 2006 Tropospheric chemistry with NMHCs included Convection: KE & TI Research Objectives: –Regional budget of O3, NOx, CO… –Improvement of model processes – wet deposition, emissions (lightning, Soil…)
