Assessment of particulate pollution in a medium sized Greek city - the effect of biomass burning and COVID-19 lockdown
(Corresponding) Diamanti V., Triantafyllou A., Garas S.
Topic:
Air pollution
Airborne particulate matter (PM) with an aerodynamic diameter of 10μm or less has severe negative effects on human health. In many European urban environments, small residential heating appliances contribute significantly to the degradation of air quality by generating a substantial quantity of PM...Read more

An integrated and comprehensive tool to assess urban mobility strategies
(Corresponding) Huertas J., Huertas M.
Topic:
Air pollution
Transport planning is a challenging topic to be addressed in urban areas in order to create sustainable cities, due to the adverse health effects, noise and congestions generated by the transport sector. Therefore, policymakers require technical tools that allow to take regulatory transport...Read more

Relationship of satellite-derived atmospheric CH4 concentrations with agriculture sector CH4 emissions in Turkey
Ceylan E., (Corresponding) Kaynak B.
Topic:
Air pollution
In this study, bottom-up annual CH4 emissions from agriculture (rice cultivation, enteric fermentation and manure) were calculated with the IPCC Tier 1 approach on county-level, and province totals were obtained for the first time in Turkey. Konya, which produces the highest annual CH4 emissions (...Read more
Application of the PALM4U Model Coupled to WRF/Chem Model to Evaluate Wind Comfort and Air Pollution Impacts for Urban Scenarios
(Corresponding) SAN NJOSE R., PEREZ CAMANYO J.
Topic:
Air pollution
Air pollution and wind comfort are both important indicators of quality of life in urban environments. This study examines the influence of a tree area (Green Park) on the wind patterns and air pollution concentrations over a downtown urban area (1 km x 1 km) in Madrid (Spain) with the CFD PALM4U...Read more
Technology hybridization for real time particulate matter monitoring
(Corresponding) Louat J., Thaury C., Ben Daoud A., Serge A.
Topic:
Air pollution
While the monitoring and management of air pollution remains a challenge at a regional level, it also becomes more and more sensitive at very local scale. Both, as hot spot sources, can be very localized, but vulnerable population (in schools, hospital…) due to fluidic effect, especially in cities...Read more

Design of Road-Side Barriers to Mitigate Air Pollution near Roads
(Corresponding) Huertas J., Aguirre J., Lopez O., Lopez C.
Topic:
Air pollution
The effects of using solid barriers on the dispersion of air pollutants emitted from the traffic of vehicles on roads located over flat areas were quantified, aiming to identify the geometry that maximizes the mitigation effect of air pollution near the road at the lowest barrier cost. Toward that...Read more

Air pollution assessment for regulatory purposes: a CFD approach design
(Corresponding) Antuña Yudego E., Fernández Pacheco V., Suárez López M., Álvarez Álvarez E., Carús Candás J.
Topic:
Air pollution
In a context of atmospheric pollution levels on the rise, there is a growing interest in the use of pollutant dispersion tools, especially for regulatory purposes involving industrial activities. Environmental organizations from different countries legislate and encourage the use of different types...Read more
Evaluation of atmospheric pollutants dispersion using CFD numerical models
Fernández Pacheco V., (Corresponding) Antuña Yudego E., Suárez López M., Carús Candás J., Álvarez Álvarez E.
Topic:
Air pollution
This paper describes the approach of studying air pollution by using Computational Fluid Dynamics (CFD) models. It also includes a report of a series of investigations performed in order to illustrate the potential of such models with the aim to give a solution to the dispersion to resolve the...Read more

Performance of a Miniaturized, Lightweight, and Cost-effective Parallel-Plate Differential Mobility Analyzer
(Corresponding) Lekaki N., Agapiou A., Costi M., Biskos G., Maisser A.
Topic:
Air pollution
Size resolved measurements of aerosol particles are essential for understanding key processes in the atmosphere, and assessing their potential impacts on human health and climate. This has led to an increasing demand for compact and portable, yet cost-effective, instruments for characterizing the...Read more

TROPOMI NO2 and SO2 Temporal Changes over Large Point Sources and Their Relationship with Electricity Production
Cingiroglu F., Deger S., Ceker A., Akyuz E., (Corresponding) Kaynak B.
Topic:
Air pollution
This study focuses on the spatial distribution and temporal changes of NO2 and SO2 pollution over large point sources using high-resolution TROPOMI retrievals, and aims to find a correlation between the retrievals and electricity production. SO2 retrievals showed highest signals over power plants,...Read more
