The Pearl River Delta (PRD) region is located on the southeast coast of mainland China and it is an important economic hub. The high levels of particulate matter (PM) in the atmosphere, however, and poor visibility have become a complex environmental problem for the region. Air quality modeling systems are useful to understand the temporal and spatial distribution of air pollution, making use of atmospheric emission data as inputs. Over the years, several atmospheric emission inventories have been developed for the Asia region. The main purpose of this work is to evaluate the performance of the air quality modeling system for simulating PM concentrations over the PRD using three atmospheric emission inventories (i.e., EDGAR, REAS and MIX) during a winter and a summer period. In general, there is a tendency to underestimate PM levels, but results based on the EDGAR emission inventory show slightly better accuracy. However, improvements in the spatial and temporal disaggregation of emissions are still needed to properly represent PRD air quality. This study’s comparison of the three emission inventories’ data, as well as their PM simulating outcomes, generates recommendations for future improvements to atmospheric emission inventories and our understanding of air pollution problems in the PRD region.

Air pollution is a global threat leading to large impacts on human health and ecosystems. In Europe, air quality remains poor in many areas, despite reductions in emissions and ambient concentrations. Air pollution and climate change are the biggest environmental concerns for Europeans, implying concerted and integrated actions to tackle them. The revised 2016 European National Emission Ceilings Directive (NECD) enforces Member States to implement strategies, based on emission reduction measures, aimed to comply with targets by 2030 and achieve European Union (EU) and World Health Organization air quality objectives for environment and health protection. Despite those strategies are designed for 2030, the influence of climate change on air quality is not accounted for. In this sense, the purpose of this paper is the evaluation of the climate change impact on future air quality, taking into consideration emission reduction measures. The WRF-CAMx air quality modelling system was applied over Europe for one year selected as representative of a short-term changing climate (around 2030), and compared to a base case year, to estimate to what extent the climate variables by themselves could positively or negatively influence air quality. Results indicate that meteorological conditions may be decisive for the air quality state in the future. Differences between future and present simulations pointed to a global decrease of ozone levels in the future; increases and decreases in particulate matter and nitrogen dioxide concentrations over different seasons and European regions. This work is intended to contribute to a better understanding of the influence of climate variables on air quality improvement strategies as an additional support to European environmental authorities in developing the National Air Pollution Control Programmes in the scope of NECD.

Toxic metals as arsenic (As), cadmium (Cd), nickel (Ni), and lead (Pb) exist in the atmosphere as particulate matter components. Their concentration levels in the European Union (EU) are regulated by European legislation, which sets target and limit values as annual means, and by the World Health Organization (WHO) that defines guidelines and reference values for those metal elements. Modelling tools are recommended to support air quality assessment regarding the toxic metals; however, few studies have been performed and those assessments rely on discrete measurements or field campaigns. This study aims to evaluate the capability of air quality modelling tools to verify the legislation compliance concerning the atmospheric levels of toxic elements and to identify the main challenges and limitations of using a modelling assessment approach for regulatory purposes, as a complement to monitoring. The CAMx air quality model was adapted and applied over Porto and Lisbon urban regions in Portugal at 5 × 5-km2 and 1 × 1-km2 horizontal resolution for the year 2015, and the results were analysed and compared with the few measurements available in three locations. The comparison between modelled and measured data revealed an overestimation of the model, although annual averages are much lower than the regulated standards. The comparison of the 5-km and 1-km resolutions’ results indicates that a higher resolution does not necessarily imply a better performance, pointing out uncertainties in emissions and the need to better describe the magnitude and spatial allocation of toxic metal emissions. This work highlighted that an increase of the spatial and temporal coverage of monitoring sites would allow to improve the model design, contribute to a better knowledge on toxic metals atmospheric emission sources and to increase the capacity of models to simulate atmospheric particulate species of health concern.

Many cities are growing and becoming more densely populated, resulting in land use changes, which promotes an increase in urban heating. Nature-based solutions (NBS) are considered sustainable, cost-effective and multi-purpose solutions for these problems. While various studies assess the effects of NBS on urban heat or urban sprawl/compaction, no studies assess their cumulative effect. The main objective of this study is to assess the short-term and medium- to long-term impacts of NBS on urban heat fluxes, taking as a case study the city of Eindhoven in The Netherlands. An integrated modelling approach, composed of a coupled meteorological and urban energy balance model (WRF-SUEWS) and an hedonic pricing simulation model (SULD), is used to assess urban heat fluxes and urban compaction effects, respectively. Results show that, in the short-term, NBS have a local cooling effect due to an increase in green/blue spaces and, in the medium to long-term, an urban compaction effect due to attraction of residents from peripheral areas to areas surrounding attractive NBS. This study provides evidence that NBS can be used to reduce the effects of urban heating and urban sprawl and that an integrated modelling approach allows to better understand its overalleffects.

In this study, the performance of two types of source apportionment models was evaluated by assessing the results provided by 40 different groups in the framework of an intercomparison organised by FAIRMODE WG3 (Forum for air quality modelling in Europe, Working Group 3). The evaluation was based on two performance indicators: z-scores and the root mean square error weighted by the reference uncertainty (RMSEu), with pre-established acceptability criteria. By involving models based on completely different and independent input data, such as receptor models (RMs) and chemical transport models (CTMs), the intercomparison provided a unique opportunity for their cross-validation. In addition, comparing the CTM chemical profiles with those measured directly at the source contributed to corroborate the consistency of the tested model results. The most commonly used RM was the US EPA- PMF version 5. RMs showed very good performance for the overall dataset (91% of z-scores accepted) while more difficulties were observed with the source contribution time series (72% of RMSEu accepted). Industrial activities proved to be the most difficult sources to be quantified by RMs, with high variability in the estimated contributions. In the CTMs, the sum of computed source contributions was lower than the measured gravimetric PM10 mass concentrations. The performance tests pointed out the differences between the two CTM approaches used for source apportionment in this study: brute force (or emission reduction impact) and tagged species methods. The sources meeting the z-score and RMSEu acceptability criteria tests were 50% and 86%, respectively. The CTM source contributions to PM10 were in the majority of cases lower than the RM averages for the corresponding source. The CTMs and RMs source contributions for the overall dataset were more comparable (83% of the z-scores accepted) than their time series (successful RMSEu in the range 25% - 34%). The comparability between CTMs and RMs varied depending on the source: traffic/exhaust and industry were the source categories with the best results in the RMSEu tests while the most critical ones were soil dust and road dust. The differences between RMs and CTMs source reconstructions confirmed the importance of cross validating the results of these two families of models.

Multiscale air quality assessment implies understanding the interaction among atmospheric processes and scales. In this perspective, the use of air quality models has a fundamental role and the way they address these interactions is very important for the quality of results. However, in multiscale air quality modelling, the relationship between models, simulation domains and resolutions remains a challenging research issue. This paper presents a state-of-the-art review on multiscale air quality modelling applications from the regional to the street level, identifying which models are used, the methodological principles and the required input datasets. Based on the findings, an analysis of the current limitations associated with the integration of different models and multiple spatial scales in a single modelling system is presented and discussed. Lastly, taking as support the reviewed contents, a set of guidelines for strengthening the synergy among scales and harmonizing different types of models within a system is proposed. Unsuitable or non-existent urban canopy parametrizations (UCP), limited grid resolutions, discarded microscale impacts on upper domains, inadequate input data and simplified chemistry are some important aspects contributing to large uncertainties when analyzing multiscale air quality results. To overcome these shortcomings in current multiscale modelling systems, more research aimed at improving the modelling performance is required, focusing on (i) UCP coupled to mesoscale models, (ii) developing modelling systems with two-way nesting capability to boost feedbacks among domains and (iii) promoting the use, improvement and development of multiscale online modelling systems, in order to have a comprehensive multiscale understanding of all atmospheric processes that govern the transport, dispersion, transformation and deposition of air pollutants.

At the global level, several epidemiological studies have conclusively pointed out the associations between short-term exposure to air pollution and acute health effects, and long-term exposure with adverse health effects such as premature mortality from severe respiratory and cardiovascular diseases. This study intended to characterize exposures and their adverse health effects. Three independent sets of vectors were analyzed on a nationwide level and annual basis: air pollutant emissions, ambient air concentrations and health indicators of the period 2009 to 2015. The emissions analysis, for the studied pollutants, pointed out the main findings: (i) Lisbon Metropolitan Area presents the most problematic region with regard to the emissions of all the pollutants under study; (ii) the regions of the Alentejo and Algarve showed reduced emissions of the studied pollutants compared to other parts of the country; (iii) Northern regions PM10 concentrations decreased during the two years in analysis. Regarding the analysis of air quality, it was concluded that: (i) regarding ozone, concentration shown a decreasing trend throughout the country; (ii) nitrogen dioxide and particulate matter, concentrations demonstrated an increasing trend in most of the northern part of the country; (iii) the regions of Alentejo and Lisbon Metropolitan Area showed increasing trends for sulfur dioxide and fine particles for the evaluated period. Decreasing trends in mortality associated with cardiovascular and respiratory causes are found mainly in the Alentejo and Algarve regions. In comparison, the North, Central regions, as well as, Lisbon Metropolitan Area exhibited higher mortality values related to this health indicators.

Pearl River Delta (PRD), located in south-eastern coast of mainland China, is one of the regions affected by heavy particulate matter (PM) levels. Notwithstanding the potential use of meteorological and air quality modelling to characterize the air pollution problems, little attention has been paid to meteorological model configuration and its impact on air quality modelling applications over the region. Aiming to find the most suitable set of parameterization schemes of the Advanced Research Weather Research and Forecasting (WRF-ARW) model for air quality modelling applications over the PRD region, a performance experiment was performed. Three tests, with different combinations of parameterization schemes, were created and evaluated. For the best configuration modelling setup, meteorological simulations for a winter (i.e. January) and summer (i.e. July) periods are provided. The meteorological model showed a clockwise deviation for the wind direction and tends to overestimate the temperature and wind speed. It is expected that the present work could reduce the meteorological and air quality modelling uncertainty over the PRD region.

The aim of this work is to explore the aerosol optical depth (AOD) data provided by different sources, namely satellite observations, air quality modelling and Aerosol Robotic Network (AERONET) observations, in order to improve characterisation of aerosol spatial distribution and to assess the contribution of the dust events on AOD over Portugal. Thus, the spatial and temporal variations of the AOD data were analysed for May 2011 taking into account the occurrence of mineral dust events. Satellite data obtained by Spinning Enhanced Visible and Infra-Red Imager (SEVIRI) instrument and air quality modelling results from the Comprehensive Air Quality Model (CAMx) over Portugal were explored. In this work, AOD values with a temporal resolution of 15 min were obtained from SEVIRI. Additionally, 3D data with 23 vertical layers for each aerosol constituent, size distribution and chemical composition were obtained from the modelling approach and used to compute the AOD at 550 nm by integrating of aerosol extinction coefficient (Qext) over the total atmospheric column. Despite the outbreaks of mineral dust occurring during this period, the overall contribution of organic carbon (OC), black carbon (BC) and sulphate (SO4) compounds to the monthly average AOD values estimated by the model is very important achieving 95% mainly located in the northern part of the studied region. The model outputs and SEVIRI data were validated with AERONET observations presenting correlation coefficients of 0.71 and 0.68 respectively. Three different modes of aerosol were classified based on Ångström coefficient versus AOD and distinguishing between the dominance of fine and coarse aerosol fractions. The analysis implemented reveal that intercomparison of satellite observations with air quality modelling contribute to better understanding of the discrepancies presented in spatial pattern of AOD.

Usually, annual emission data from residential combustion sector are spatially disaggregated by population density to the sub-municipality spatial level. The aim of the present work is to define a methodological approach to develop/build a high-resolution emission inventory from residential combustion following a bottom–up approach. The conceptual model considers different approaches by fuel category (solid fuel–wood, gas and liquid fuels) according to distinct spatial coverage and type of activity data available for each category. For solid fuels, detailed activity data (per district), disaggregated according to the number and type of equipment, burned wood species and consumption rate, as well as specific emission factors (per wood species) were used. With regard to the gas and liquid fuels, the total national emission by fuel type using national consumption data and broader emission factors was disaggregated to the sub-municipality scale based only on the number of heating equipment. The choice of these disaggregation factors was influenced by both data availability and relevance. The results of the new disaggregated emission data have been compared with emission values resulting from the classical top–down approach using census/population data. The selected case study is Portugal. The results pointed out that major differences exist when comparing both approaches, namely regarding the spatial distribution/allocation of emissions. In the new approach, emissions are more redistributed over the territory, while in the old distribution, emissions are concentrated in the coastal urban areas (with hotspots in the main urban areas of Porto and Lisbon).

Considering different resilience measures such as the increase of urban green areas and the application of white roofs, a set of resilience scenarios were evaluated with a cascade of numerical models (MPI-ESM-LR/WRF/CAMx) using as case study a future heat wave occurring in Porto (Portugal) urban area. Meteorological forcing and boundary data was derived from the CMIP5 earth system model MPI-ESM (Representative Concentration Pathway RCP 8.5) downscaled to Porto urban area. The influence of different resilience scenarios on the air quality was quantified and compared for the different scenarios. The results show that all tested measures lead to an increased resilience to CC impacts, promoting the reduction of ozone concentrations. The application of green roofs was the measure that shows more benefits to air quality.

The national emission ceilings (NEC) Directive was implemented to contribute to the reduction of transboundary air pollutions impacts, limiting emissions of acidifying and eutrophication pollutants as well as ozone precursors. It was first adopted by the European Commission (EC) in 2001 (Directive 2001/81/EC) covering four pollutants (NOx, SO2, NH3 and NMVOC). Under the scope of the clean air programme for Europe, which established the air policy objectives for 2020 and 2030, a new NEC was adopted (Directive 2016/2284/EU) establishing more strict ceilings for those pollutants and adding as well PM2.5. The objective of this paper is to analyse the evolution of the Portuguese national emissions and the compliance of NEC Directive in 2010 and to foresee if the new ceilings for 2030 will be fulfilled. The emission inventories reported to the EC show that emissions in Portugal presented a consistent decreasing trend for all pollutants from 2000 to 2014, and a slight increase in 2015. The 2010 targets were achieved with measures implemented at the time (particularly on the energy, industrial combustion and transport sectors) which allowed Portugal to even surpass the defined goals. The emission projections for 2030, however, reveal that necessary emission reductions for all pollutants could be attained only if measures of the most demanding scenarios are implemented. Therefore, an integrated strategy should be designed and implemented aiming to not only fulfil the NEC in 2030 but also guarantee a better air quality with the highest cost-benefit for the environment and health.

Air pollution is, increasingly, a concern to our society given the threats to human health and the environment. Concerted actions to improve air quality have been taken at different levels, such as through the development of Air Quality Plans (AQPs). However, air quality impacts associated with the implementation of abatement measures included in AQPs are often neglected. In order to identify the major gaps and strengths in current knowledge, a literature review has been performed on existing methodologies to estimate air pollution-related health impacts and subsequent external costs. Based on this review, the Impact Pathway Approach was adopted and applied within the context of the MAPLIA research project to assess the health impacts and benefits (or avoided external costs) derived from improvements in air quality. Seven emission abatement scenarios, based on individual and combined abatement measures, were tested for the major activity sectors (traffic, residential and industrial combustion and production processes) of a Portuguese urban area (Grande Porto) with severe particular matter (PM10) air pollution problems. Results revealed a strong positive correlation between population density and health benefits obtained from the assessed reduction scenarios. As a consequence, potential health benefits from reduction scenarios are largest in densely populated areas with high anthropic activity and, thus, where air pollution problems are most alarming. Implementation of all measures resulted in a reduction in PM10 emissions by almost 8%, improving air quality by about 1% and contributing to a benefit of 8.8 million €/year for the entire study domain. The introduction of PM10 reduction technologies in industrial units was the most beneficial abatement measure. This study intends to contribute to policy support for decision-making on air quality management.

When ambient air quality standards established in the EU Directive 2008/50/EC are exceeded, Member States are obliged to develop and implement Air Quality Plans (AQP) to improve air quality and health. Notwithstanding the achievements in emission reductions and air quality improvement, additional efforts need to be undertaken to improve air quality in a sustainable way - i.e. through a cost-efficiency approach. This work was developed in the scope of the recently concluded MAPLIA project "Moving from Air Pollution to Local Integrated Assessment", and focuses on the definition and assessment of emission abatement measures and their associated costs, air quality and health impacts and benefits by means of air quality modelling tools, health impact functions and cost-efficiency analysis. The MAPLIA system was applied to the Grande Porto urban area (Portugal), addressing PM10 and NOx as the most important pollutants in the region. Four different measures to reduce PM10 and NOx emissions were defined and characterized in terms of emissions and implementation costs, and combined into 15 emission scenarios, simulated by the TAPM air quality modelling tool. Air pollutant concentration fields were then used to estimate health benefits in terms of avoided costs (external costs), using dose-response health impact functions. Results revealed that, among the 15 scenarios analysed, the scenario including all 4 measures lead to a total net benefit of 0.3M€·y(-1). The largest net benefit is obtained for the scenario considering the conversion of 50% of open fire places into heat recovery wood stoves. Although the implementation costs of this measure are high, the benefits outweigh the costs. Research outcomes confirm that the MAPLIA system is useful for policy decision support on air quality improvement strategies, and could be applied to other urban areas where AQP need to be implemented and monitored.

Agriculture is the main source of atmospheric ammonia (NH3). Methodologies are needed to quantify national NH3 emissions. For European continental scale the EMEP emissions inventory with a 50 × 50 km2 resolution is yearly available. However, current air quality models are often applied with higher spatial resolution, in order to obtain representative results, especially at urban and regional scales; therefore, a simple top-down approach based in the spatial interpolation of EMEP emissions is not sufficient. The aim of this work is the development and application of a mixed top-down and bottom-up methodology for high resolution emissions inventory for the agriculture sector, based on EMEP and other public data sources (E-PRTR inventory, statistical data, etc.) for Western Spain and Portugal. This new emission inventory was compared with EMEP and assessed using the WRF-CAMx air quality modelling system. Results highlighted the influence of the meteorology (high temperatures) and the magnitude of emissions on NH3 air quality concentrations. The higher resolution emissions lead to the highest maximum NH3 ground level concentrations, in specific locations.
