Tesis doctoral de Rene Parra Narvaez
Photochemical pollution episodes by ozone take place in catalonia, mainly during the summertime. The complex ozone behaviour, its interactions with the atmosphere and the effects on air quality could be understood by modelling, using a chemical transport model (ctm). Emission inventories provide the information of the spatial and temporal emissions distribution of the ozone precursors and other pollutants required by this kind of approach. emicat2000 is an emission model with high spatial (cells of 1 km2) and temporal (1 hour) resolutions, which was developed into a gis environment to estimate the emissions from catalonia during the year 2000. It includes the most important primary air pollutants (nox, nmvocs, co, so2 and tsp) and greenhouse gases (co2, ch4 and n2o). Emicat2000 integrates daily, monthly and yearly emissions, providing information both for environmental policy and photochemical modelling. this model includes the emissions from vegetation, on-road traffic, most important industries and emissions by fossil fuel consumption and domestic-commercial solvent use. the nmvocs emission model from vegetation (isoprene, monoterpenes and other nmvocs) uses the algorithm by guenther et al. (1993), suited and adapted for describing 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 vast database of hourly records of superficial temperature and solar radiation was incorporated. the 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 > 3000). emicat2000 uses the methodology and emission factors of the european model emep/corinair – copertiii as basis, and includes monthly, daily and hourly traffic profiles; differe
