Atmospheric dispersion modelling of particulate and gaseous pollutants affecting the trans-Manche region
… determine large-scale and meso-scale atmospheric dispersion patterns. The research is only concerned with outdoor exposure to atmospheric pollutants and aims to identify pollution sources using dispersion modelling with the assistance of ground level measurements from British, French and other …

Air pollution modelling for the greater Cape Town region
Limited research on dispersion modelling for the Cape Town metropolitan area has been undertaken. This thesis deals with air-pollution aspects in relation to dispersion modelling, as well as with the input requirements and application of a dispersion model in the Greater Cape Town region. An EPA …

A dynamic knowledge graph approach to creating interoperability in smart cities: Selected case studies towards holistic flood impact assessments and district heating operations
… is highlighted by integrating airborne emission dispersion modelling with the dynamic control of a district heating network. An agent-based implementation is developed to forecast the anticipated heat demand, minimise associated total generation cost, and couple it with dispersion modelling of …

Development of a method for estimating methane gas emissions at high resolution
… atmospheric methane measurements and computer dispersion modelling into a statistical technique. Methane emission estimates are inferred using cost function analysis within a simulated annealing method. This thesis presents results covering a two year period (July 2012 - June 2014) in which …

Risk and safety assessment of an alkaline electrolyser system for green hydrogen production
… of hydrogen specific failure rate data. Gas dispersion modelling was performed using ALOHA software for two locations, i.e., near Moorreesburg and the port of Saldanha. Results showed that hydrogen release from a 250 m3 storage presents the highest risk compared to release from a 200 m pipe …

An operational method for assessing traffic-related air pollution in urban streets
… streets, after testing available monitoring and modelling techniques. To meet this objective, a large amount of original air quality, meteorological and traffic data were collected during four intensive short-term and one long-term monitoring campaigns carried out in the region of Paris from …

Assessing PM2.5 pollution and the role of transboundary pollution emissions across Greater Kuala Lumpur, Malaysia from 2018 to 2023
… masses across GKL using Numerical Atmospheric-dispersion Modelling Environment (NAME), and iv) predicting PM2.5 levels in GKL using NAME-GFAS model during transboundary haze. Over the six years, three primary PM2.5 pollution features were observed: i. a significant peak in 2019, ii. a marked …

‘Organics in ice’: Novel organic compounds in ice cores for use in palaeoclimate reconstruction
… data, and by application of back trajectory modelling using the Met Office's Numerical Atmospheric-dispersion Modelling Environment (NAME). In the case of Bouvet Island, the fatty acid oleic acid is found to have statistically significant correlations with the sea-ice marker methanesulfonic …

Modelling of Air Pollution and Evaluation of the Human Health Implication in Phalaborwa, Mopani District, South Africa
… Protection Agency Regulatory Model (AERMOD) dispersion modelling was used to model the dispersion of major emission sources of PM2.5 and PM10 within the community. The AERMOD model uses the five pathways including control, sources, receptor, meteorological and output to generate the spatial …

Modelling atmospheric dispersal of fungal pathogens on continental scales to safeguard global wheat production
… UK Met Office’s Langrangian stochastic particle dispersion model, NAME, is applied, extended and coupled to other models in a set of case studies. In the first case study, spore dispersal is analysed across Southern/East Africa, the Middle East, and Central/South Asia by simulating billions of …
