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

Vegetation

• 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.

On-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 gt 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. Hot exhaust emissions model

Integration of emissions files into Models-3/CMAQ

• Text emission files are built in two sections
• 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 i1 ROW, j1 COL, k1 LAY
  being ROW, COL, and LAY the number of rows,
  columns and layers, defining domain

Conclusions
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
