Short summary
Short summary
Within the Copernicus Atmosphere Monitoring Service (CAMS), a forecasting system calculating the city source contribution for the surface urban background PM10 in European cities has been developed. The system uses the EMEP model and this paper presents the product by focusing on an event which occurred from 1 to 9 December 2016.

Short summary
This study examines NH3 emissions from UK agriculture and the role it plays in PM2.5 formation, focusing on the dairy, pig, and poultry sectors. Using regional and local air quality models, we find that a 13 % NH3 reduction cuts PM2.5 by only ~1 % due to NH3-rich air. The regional model may underestimate PM2.5, while the local modelling shows that emissions disperse within 700 m. The study highlights the value of combining models to better understand the spread of pollutants and to improve PM2.5 control strategies.
