Abstract: Different operational air quality forecasts (ESSEM Cost Action 0602) are currently available in Europe. However, most of them are not suitable for regional application and, also, their coarse outputs do not fit well with air quality management needs. In this work, PRESAXIO regional air quality modelling system is validated and applied over Galicia (NW of Spain), including WRF and CHIMERE models. WRF validation is done by comparison with surface meteorological measurements; CHIMERE validation applies DELTA tool with AirBase data. PRESAXIO applications include an operational air quality forecast, design of a regional air quality monitoring network, and impact assessment of EMEP emissions changes in regional O₃ peaks.

Keywords: PRESAXIO air pollution modelling; WRF; CHIMERE; DELTA tool; air quality networks; network design; EMEP emissions changes; regional air quality; Spain; atmospheric dispersion modelling.
