Development of the high spatial resolution EMICAT2000 emission model for air pollutants from the north-eastern Iberian Peninsula (Catalonia, Spain)

Ozone (O₃) pollution episodes take place in Catalonia (NE of the Iberian Peninsula), mainly during summertime. The complex O₃ behaviour could be understood by using a Chemical Transport Model (CTM). Emission inventories provide the spatial and temporal emissions distribution of the O₃ precursors and other pollutants required by this approach. We developed the EMICAT2000 model with high spatial (cells of 1 km²) and temporal (1 h) resolutions, to estimate the emissions during the year 2000 from Catalonia. Total annual emissions were 107 kt yr^-1 of NO _x, 137 kt yr^-1 of NMVOC, 267 kt yr^-1 of CO, 65 kt yr^-1 of SO₂, 24 kt yr^-1 of TSP and 32 175 kt yr^-1 of equivalent CO₂. Main NO_x sources are on-road traffic (58%) and industries (38%). Main NMVOC sources are on-road traffic (36%), vegetation (34%) and use of solvents (13%). Speciation was established according to the Carbon Bond IV mechanism. EMICAT2000 generates directly the data files required for the third generation CTM Models-3/CMAQ.
