| Two air quality field campaigns were performed in 2015 during winter and summer in a complex traffic hotspot in Madrid. Apart from gaseous species, the ambient particulate mass concentration levels (PM10, PM2.5 and PM1) were measured at different atmospheric conditions. Several Optical Particle Counter instruments were deployed in the study area, two of them installed at two points in the North ?South axis. A DustTrak DRX measured the particle levels around the experimental area following a dynamic measurement pattern. These instruments were previously validated against the reference gravimetric method and against a TEOM instrument. Particle measurements were complemented with meteorological and microturbulence parameters from two stations located in the study area (0.42 km2). Results evidence the great heterogeneity in horizontal concentration fields and observed spatial distributions that follow complex atmospheric dynamic patterns. Localemissions present very short-time variations and traffic lights schedule seem to be relevant for exhaust emissions at these hottest sites The pedestrian flows were also characterized to obtain their exposure to ambient particles. | |
