| Zusammenfassung |
| This paper presents the summary of the key objectives, instrumentation and
logistic details, goals, and initial scientific findings of the European
Marie Curie Action SAPUSS project carried out in the western Mediterranean
Basin (WMB) during September–October in autumn 2010. The key SAPUSS
objective is to deduce aerosol source characteristics and to understand the
atmospheric processes responsible for their generations and transformations
– both horizontally and vertically in the Mediterranean urban environment.
In order to achieve so, the unique approach of SAPUSS is the concurrent
measurements of aerosols with multiple techniques occurring simultaneously in
six monitoring sites around the city of Barcelona (NE Spain): a main road
traffic site, two urban background sites, a regional background site and two
urban tower sites (150 m and 545 m above sea level, 150 m and 80 m above
ground, respectively). SAPUSS allows us to advance our knowledge sensibly of
the atmospheric chemistry and physics of the urban Mediterranean environment.
This is well achieved only because of both the three dimensional spatial
scale and the high sampling time resolution used. During SAPUSS different
meteorological regimes were encountered, including warm Saharan, cold
Atlantic, wet European and stagnant regional ones. The different meteorology
of such regimes is herein described. Additionally, we report the trends of
the parameters regulated by air quality purposes (both gaseous and aerosol
mass concentrations); and we also compare the six monitoring sites. High
levels of traffic-related gaseous pollutants were measured at the urban
ground level monitoring sites, whereas layers of tropospheric ozone were
recorded at tower levels. Particularly, tower level night-time average ozone
concentrations (80 ± 25 μg m−3) were up to double
compared to ground level ones. The examination of the vertical profiles
clearly shows the predominant influence of NOx on ozone
concentrations, and a source of ozone aloft. Analysis of the particulate
matter (PM) mass concentrations shows an enhancement of coarse particles
(PM2.5–10) at the urban ground level (+64%, average
11.7 μg m−3) but of fine ones (PM1) at urban tower level
(+28%, average 14.4 μg m−3). These results show
complex dynamics of the size-resolved PM mass at both horizontal and vertical
levels of the study area. Preliminary modelling findings reveal an
underestimation of the fine accumulation aerosols. In summary, this paper
lays the foundation of SAPUSS, an integrated study of relevance to many other
similar urban Mediterranean coastal environment sites. |
