Abstract

This dataset contains the observations of air quality collected within one experimental campaign conducted in August 2018 at Lazzaretto campus of the University of Bologna to verify the effectiveness of photocatalytic coatings in reducing pollutant concentrations. The dataset also contains the meteorological data collected during non-synoptic periods, representing the ideal condition to assess the behavior of the local circulation and turbulence. This experimental field campaign was conducted under WP3 (“Planning and evaluation of PCS solutions”) of the iSCAPE project. Briefly, two parallel street canyons were instrumented for measurements of meteorology and turbulence variables at two height levels, while pollutant concentrations were monitored at ground level inside both canyons. After a first period of parallel contemporary measurements to verify the presence of intrinsic differences between the two canyons, one of the two canyons (Canyon A) was painted with photocatalytic coatings, while the other (Canyon B) was left untouched and used as reference canyon. This dataset is linked to the paper “The effect of photocatalytic coatings on NOx concentrations in real-world street canyons” by Brattich E. et al., which has been submitted for publication on “Science of the Total Environment” edited by Elsevier. If you use this dataset for your research or work purposes, we ask that you acknowledge us in the use of your data, which can be done by including a proper citation in any documents or publications using these data.
