A spatially and temporally resolved atmospheric emission inventory of ozone precursor pollutants (NOx, NMVOCs and CO) was developed for the southern Balkan region in order to support air quality modelling studies focusing on Greece. The inventory is established for the reference year 2000 and it has 10 km spatial resolution. Annual anthropogenic emission data obtained from official national emission inventories and from international emission databases were spatially disaggregated and allocated to a gridded domain using the top-down methodology. Source specific temporal profiles were used in order monthly and hourly emission data to be estimated. In the study area, the highest NOx amounts are emitted by the maritime and road transport sectors. Road transport has a prominent role in anthropogenic NMVOCs emissions followed by the solvent and other product use sector. The main CO emission sources are represented by the road transport sector and the non-industrial combustion plants. In the present study, the contribution of the transport sector to the total emissions of pollutants over urban and non-urban areas of Greece is investigated. Over almost all Greek urban areas, road transport is the major NMVOCs and CO emission source. Road transport contribution to NOx emissions is greater than 50% at the large urban centres of Greece. The greater part of non-urban areas is dominated by off-road vehicle emissions.
