Abstract. The North Atlantic Oscillation (NAO) controls a large amount of the European climate variability with asymmetric impacts in both time and space. Here we investigate how the NAO impact on the local atmospheric processes (disregarding the NAO impact on the large intercontinental transport mechanisms) influences the levels of various aerosol species using simulated data under constant emissions, which are fixed to the 2005 levels in order to avoid anthropogenic-induced signals. In particular, we analyze interannual variations at the seasonal timescale and focus on the ground-level. The results show that positive NAO phases favor increased aerosol concentrations in southern (northern) regions during winter (summer), while negative NAO phases enhance them in northern (southern) regions during winter (summer). The underlying processes are clearly related to the NAO impact on precipitation and wind, as they act to clean the atmosphere through removal and dispersion processes, and to the NAO impact on the radiation balance (i.e., cloudiness) as it affects the biogenic emitting activity and on the oxidative capacity of the atmosphere. Differences for all the species studied (natural inert, secondary inorganic and organic aerosols) are up to 5 µg m −3 , reaching 10 and 20 µg m −3 for PM 10 and PM 2.5 respectively, which represents variations of about 20-40 % in their mean levels between opposite NAO phases.

Climate change and air pollution, both on a global and local scale, are two interrelated environmental policy problems, but usually they are studied separately with very different approaches. In a novel context, in which climate change and air quality become two related aspects of the same problem, we believe that it is necessary to carry out novel local strategies for Air Quality Monitoring Networks' (AQMNs) innovation, not only applying analytical optimization procedures of the existing networks, but also introducing advanced in situ devices and using data by remote investigations. Advanced instrumentation allows to evaluate the concentration of specific pollutants and to better characterize the local weather conditions. Remote observations (satellite data and vertical profiles of atmospheric variables) may improve the network effectiveness. In this study we present experimental data observed in the urban area of Potenza (Basilicata, southern Italy) during a field survey. In the same sampling period, we compare data atmospheric pollutants concentrations by AQM network of Potenza with data collected in our experimental site and with a satellite map of CO 2 . Despite the observation scales being very different, the results are encouraging and we believe that other efforts have to be made; the short-term benefits obtaining from air pollution control and innovation may be as effective as the long-term benefits obtainable through strategic climate change measures. So it is important to develop and to support local integrated strategies, for mitigating air pollution and climate change contemporaneously.
