“…Similarly, Danek and Zareba, 2021 present a study assessing the air quality in the city of Krakow, Poland, using LCS data. The main findings of this study highlight that air pollution episodes during winter in Krakow are mainly caused by the use of solid fuel for residential heating in the neighbouring cities [ 24 , 38 ]. Usually, these episodes occur during cold nights, with high atmospheric stability and especially when thermal inversions occur in the lower atmosphere, the ideal conditions to reduce the dilution of pollutants in the atmosphere.…”

Within the scope of the Aveiro STEAM City project, an air quality monitoring network was installed in the city of Aveiro (Portugal), to evaluate the potential of sensors to characterize spatial and temporal patterns of air quality in the city. The network consists of nine sensors stations with air quality sensors (PM10, PM2.5, NO2, O3 and CO) and two meteorological stations, distributed within selected locations in the city of Aveiro. The analysis of the data was done for a one-year measurement period, from June 2020 to May 2021, using temporal profiles, statistical comparisons with reference stations and Air Quality Indexes (AQI). The analysis of sensors data indicated that air quality variability exists for all pollutants and stations. The majority of the study area is characterized by good air quality, but specific areas—associated with hotspot traffic zones—exhibit medium, poor and bad air quality more frequently. The daily patterns registered are significantly different between the affected and non-affected road traffic sites, mainly for PM and NO2 pollutants. The weekly profile, significative deltas are found between week and weekend: NO2 is reduced on the weekends at traffic sites, but PM10 is higher in specific areas during winter weekends, which is explained by residential combustion sources.

“…To assess the future climate and air quality patterns on the study area, the WRF -Weather Research and Forecasting Model [23] together with the CAMx -Comprehensive Air Quality Model with Extensions [24] modelling framework was applied. These models have been widely used to assess air pollution in different case studies worldwide, and more specifically in Portugal, with reliable and realistic results [12,17,25].…”

“…According to the Sixth Assessment Report of the Intergovernmental Panel on Climate Change (IPCC) [13], it is expected that climate change will have complex effects on chemistry, transport and deposition of local air pollutants. IPCC also refers to urban areas as the ones that must respond to climate change risks [13,14], mostly due to the complex interactions between social, economic, and environmental stressors [15][16][17]. Indeed, climate change impacts in urban areas has recently become an important and urgent research topic.…”

“…The Aveiro Region is located in the central part of Portugal, close to the Atlantic Ocean, with an area of 1 693 km 2 and around 370 000 inhabitants. The Aveiro Region includes eleven municipalities which are distinguished by their geography, economy, activity sectors and population density [17,19]. The major economic sector of the region is manufacturing industry, accounting for 50% of the region's income [20], followed by tourism and services [19].…”

“…According to the Köppen climate classification [22], Aveiro Region is classified as a warm-summer Mediterranean climate (Csb). Despite the climate and the open landscape characteristic of many of the municipalities in the Aveiro Region, which favor the pollutants dispersion, PM and NO2 exceedances occur occasionally in some areas of the region [17,19].…”

The World Health Organization estimates that every year air pollution kills seven million people worldwide. As it is expected that climate change will affect future air quality patterns, the full understanding of the links between air pollution and climate change, and how they affect human health, are challenges of future research. In this scope, a methodology to assess the air quality impacts on health was developed. The WRF-CAMx modelling framework was applied for the medium-term future climate (considering the SSP24.5 scenario) and for the recent past (considered as baseline). Following the WHO recommendations, mortality health indicators were used to estimate health impacts of long-term exposures. For that, the Aveiro Region, in Portugal, was considered as a case study. Future climate results indicate the occurrence of higher temperatures, and lower total precipitation. Despite that, improvements in the main pollutants’ concentrations, and consequently in the reduction of the related premature deaths are foreseen, mainly due to the reduction of pollutants emissions imposed by the European legislation for the upcoming years. The applied approach constitutes an added value in this research field, being crucial to anticipate the effects of climate change on air quality and evaluate their impacts on human health.
