High ozone, ultrafine particles and secondary aerosol episodes in urban and regional backgrounds in NE Spain.
The HOUSE project aims at investigating the atmospheric scenarios and processes yielding to the high formation rates of ozone (O3), ultrafine particles (UFP) and secondary aerosols (SA) typical of the Western Mediterranean Basin in summer. In this area the formation of high levels of these atmospheric constituents take place in a very complex system in which solar radiation, humidity, temperature, volatile organic compounds, inorganic gaseous pollutants, halogens, radicals, ozone and ultrafine particles play a major role.
The analysis of these processes is important for policies focusing on abatement of both climate forcing and health-ecosystems effects of air pollution.
The HOUSE project will provide important information for designing and assessing air quality and climate plans for abating photochemical pollutants in Spain. Within the HOUSE project the optical characterization of tropospheric aerosols will consist of both ground and columnar measurements performed at the Montseny and Montsec
GAW/ACTRIS stations. The obtained extensive and intensive aerosol optical measurements will be related with the physical and chemical measurements of aerosols in order to derive site-specific aerosol optical parameters considered as fundamental inputs for climate models and policies.
