The influence of atmospheric circulation and meteorology on urban air pollution and pollen exposure
Urban air quality is a global health concern and is a growing problem due to large migration of people from rural areas to cities, a phenomenon occurring in many parts of the world. This means that more and more people can be expected to be exposed to high levels of air pollutants, many of which are...

Urban air quality is a global health concern and is a growing problem due to large migration of people from rural areas to cities, a phenomenon occurring in many parts of the world. This means that more and more people can be expected to be exposed to high levels of air pollutants, many of which are associated with the urban environment. The exposure situation is characterised by different compounds emitted from different sources such as traffic, industry, wood burning and energy production. Air pollution levels tend to vary temporally both during the day and between seasons. Another important atmospheric constituent to consider is pollen which together with air pollutants can cause severe health effects in sensitive people. The climate and weather governs the atmospheric processes responsible for ventilation and stagnation of the air, which in turn also provides conditions for good or poor air quality. This thesis has investigated the urban air pollution levels of nitrogen oxides (NOx = NO + NO2), ozone (O3), particles (PM10 and PNC, particle number concentration) and birch pollen levels in relation to meteorology and atmospheric circulation. In this study circulation was represented by the large scale circulation pattern called the North Atlantic Oscillation (NAO) and by the synoptic circulation classification scheme Lamb Weather Types (LWT).
