Introduction
Emission inventories files required by Models-3/CMAQ for applications in the United States are processed by tools such as MEPPS or SMOKE, integrating national or regional emission databases with results by emission models (e.g. MOBILE6, BEIS3)
Application and exploitation of Models-3/CMAQ in other regions is conditioned to the applicability and potential adaptation of these emission tools
We developed the EMICAT2000 emission model for its implementation within Models-3/CMAQ applications in the northeastern Iberian Peninsula (Catalonia, Spain). Air pollutants emissions are related with ozone (O3) pollution episodes. EMICAT2000 is a GIS emission model developed with high spatial (1 km2) and time (1 h) resolutions

VegetationVegetation
The emission model from vegetation (isoprene, monoterpenes and other NMVOCs) describes the particular emitter behaviour of some Mediterranean species. Emission factors by land-use categories were defined, as result of an exhaustive selection of emission factors of the most important vegetal species. A huge database of hourly records of superficial temperature and solar radiation was incorporated. Isoprene emission model (Guenther et al. 1993)

On-road trafficOn-road traffic
Emission model includes the hot exhaust, cold exhaust and evaporative emissions, using a digital map of the all the highways and the most important roads and streets (daily average traffic > 3000). EMICAT2000 uses the method and emission factors of the European model EMEP/CORINAIR – COPERTIII, and includes monthly, daily and hourly traffic profiles; differencing the vehicle park composition between weekdays and weekends.

Integration of emissions files into Integration of emissions files into Models-3/CMAQModels-3/CMAQ
Text emission files are built in two sections:
1) the header, containing information about the configuration of the study domain
2) the emission data organized according to the netCDF protocol. Figure shows the arrangement of rows and columns on the XY plane. Indexes follow the relations: i+1 = ROW, j+1 = COL, k+1 = LAY; being ROW, COL, and LAY the number of rows, columns and layers, defining domain

ConclusionsConclusions
We developed the EMICAT2000 model, which estimates emissions for the complex configuration of Catalonia (northeastern Iberian Peninsula). This model provides directly the emission files required by Models-3/CMAQ
Successful results of O3 modelling are currently obtained (Jiménez et al., 2004)
This approach could be considered for similar exploitation of Models-3/CMAQ in different regions worldwide
