Air pollution and meteorology monitoring report (Update). Deliverable 5.2(Update). Project iSCAPE, Grant Agreement number: 689954

This is the updated version of D5.2, whose aim is to document good quality meteorological and air pollution data obtained in the various experimental field campaigns carried out in the different iSCAPE cities, namely Bologna, Dublin, Guildford and Vantaa. Experimental field campaigns were setup and carried out in those iSCAPE cities with a specific focus on the evaluation of the impacts on Passive Control Systems (PCSs) on the mitigation of air pollution and the enhancement of urban thermal comfort (i.e., Bologna in Italy, Dublin in Ireland, Guildford in United Kingdom and Vantaa in Finland), while the other two iSCAPE cities (Bottrop in Germany and Hasselt in Belgium) focused instead on infrastructural and behavioral interventions only, and no dedicated experimental field campaign was setup within the iSCAPE project. As mentioned in the first version of this Deliverable, the campaigns were ad-hoc setup with two preliminary purposes: 1. To provide the scientific basis to evaluate the impact of different PCSs and other meteorological factors on air pollution in each city; 2. To gather data useful to verify the model simulations run as part of other WPs (e.g., WP4 and WP6) with the aim of evaluating the impact of infrastructural and behavioral interventions at larger scales (neighborhood and urban). Similar to the first version of this report, before presenting the specific results obtained in each city, the updated version presents the instrumental setup and methodologies adopted in the various field campaigns, summarizing and updating those previously presented in D3.3 (‘Report on footprint of PCSs1’) and in the first version of this Deliverable. Notwithstanding the difference in the experimental setups adopted in the various experimental campaigns, a common general result obtained is the strong dependency of the impact of the different PCSs on the local morphology of the analyzed urban environment and on the local meteorological conditions, among which in particular wind direction plays a dominant role, leading potentially to both mitigation and deterioration effects of air pollution. In addition, in Guildford colocation experiments of low-cost sensors with reference instrumentation were carried out to develop algorithms to analyze the data from low-cost sensors and to investigate the performance of low-cost sensors.
