Description
The photochemical reactions in atmosphere take place in a very complex system in which solar radiation, humidity, temperature, volatile organic compounds (VOCs), including biogenic ones (BVOCs), inorganic gaseous pollutants (NOx, NH3, SO2), halogens (I, Cl, Br), radicals, O3 and ultrafine particles (UFP, those <100nm) play major roles. The generation of O3, UFP and secondary aerosols (SA) from this system is a hot topic in atmospheric science, but also for air quality. The horizontal and vertical variation of O3 and UFP is poorly experimentally described in both urban and regional backgrounds; and this is of special relevance in the Western Mediterranean where specific meteorological, geographic and emission patterns results in enhanced photochemistry. In this area O3 and UFP are recorded in high levels and are important for policies focusing on abatement of both climate forcing and health-ecosystems effects of air pollution. Another important sub-product of this NOx catalysed system is the organic SA (SOA), from both anthropogenic (ASOA) and enhanced biogenic (eBSOA) origins.
Objectives
i) investigating the spatial variability of O3 and UFP in NE Iberian Peninsula where these air quality parameters are of special relevance; and
ii) analysing the atmospheric scenarios yielding to high formation rates of O3, UFP, SOA and inorganic SA (SIA) in the Western Mediterranean. Our final aim is providing experimental results describing the atmospheric episodes yielding to high levels of these pollutants and to investigate the source origins (natural/anthropogenic, local/regional/hemispheric) based on results from specially designed measurement campaigns with state of the art instrumentation for UFP (PSM), aerosols (TAG-AMS, ACSM), VOCs (HR-PTR-MS), airborne measurements (balloons) equipped with miniaturised instruments, passive dosimeters and long term measurements. The results will be integrated with those from the existing ground based and vertical measurements carried out in the IDAEA air quality experimental to support building of new knowledge as well as policy issues on climate change, air quality, and long-range transport of pollutants.
Our results on the photochemical pollution episodes coupled with modelling outputs from other teams and projects developed will provide important information for designing and assessing air quality plans for abating photochemical pollutants in Spain.
Field campaign
In the framework of HOUSE we are organizing a field campaign in July 2017 that will take place in Northern Barcelona area (Vic, Montseny, Barcelona). The campaign is focused on ozone and photochemical precursors and will consist of three major activities:
1. Ozone measurements by using passive dosimeters, conventional monitors and sensors covering a large spatial area northern Barcelona, during July 2017.
2. Intensive measurements of O3, ultrafine particles, clusters and gaseous precursosrs (VOCs and NOx) at Montseny and Barcelona, July 4th to 20th 2017.
3. Vertical profiles of O3, UFP, BC, by using instrumented tethered balloons, during measurements of UFP and O3. July 10th to 14th 2017.

As you were informed, HOUSE proposal was accepted and formally stated in January 2017. This is supported by the National Science Foundation of Spain and covers only research budget for Spanish teams, but there is also economic support for travelling and expenses of foreign teams involved in the campaigns.
