Manders, A.M.M. (author), Ketzel, M. (author)Air quality in Europe has been considered an issue since the 1950s and has improved considerably over the past decades. Emissions in 2018 were reduced considerably as compared to 2005, with emission reductions of SOx of more than 50%, of NOx of about 40% and of PM10 of about 25%. Nowadays, many areas comply with the limit values of the European...bookPart 2023

(author), Fishwick, J. (author), Yang, M. (author)Global concerns regarding air quality have over the past decade led to the introduction of regulations by the International Maritime Organisation curbing the emissions of sulphur and nitrogen oxides (SOx, NOx). These limits were implemented initially in so-called “emission control areas”, defined where the density of shipping activity combines...article 2023

(author), Quintero, O.L. (author)Chemical transport models (CTM) are crucial for simulating the distribution of air pollutants, such as particulate matter, and evaluating their impact on the environment and human health. However, these models rely heavily on accurate emission inventory and meteorological inputs, usually obtained from reanalyzed weather data, such as the...article 2023

Deng, T. (author), Manders, A.M. (author), Jin, J. (author), Lin, H.X. (author)Ground-level ozone is a critical atmospheric pollutant, and high concentrations of ozone can damage human health, affect plant growth and cause ecological harm. Traditional chemical transport models and popular machine learning models have difficulty in predicting ozone concentrations, especially in times with high concentrations. We proposes a...article 2022

Thunis, P. (author), Clappier, A. (author), Pisoni, E. (author), Bessagnet, B. (author), Kuenen, J. (author), Guevara, M. (author), Lopez-Aparicio, S. (author)Some studies show that significant uncertainties affect emission inventories, which may impeach conclusions based on air-quality model results. These uncertainties re sult from the need to compile a wide variety of information to estimate an emission inventory. In this work, we propose and discuss a screening method to compare two emission...article 2022

Xu, M. (author), Jin, J. (author), Wang, G. (author), Segers, A. (author), Deng, T. (author), Lin, H.X. (author)Air quality warning and forecasting systems are usually based on numerical chemical transport models (CTMs). Those dynamic models perform predictions by simulating the life cycles of the atmospheric components, including emission, transport and removal. However, the accuracy of these CTMs are still limited because of many imperfections, e.g.,...article 2021
