New Avenues in Atmospheric Modelling of Exoplanets
In this thesis I explore various aspects of atmospheric characterisation of exoplanets with the primary goal of understanding their chemical compositions and physical processes. My research led to the development of new self-consistent models of exoplanetary atmospheres, a new paradigm for …

Sea surface temperature anomalies in the South Indian ocean : observations and atmospheric modelling
… South Indian Ocean. In order to investigate the atmospheric response over Southern Africa to this phenomenon, this study uses the MM5 regional climate model in which the model is forced with a warm pole SST anomaly south of Madagascar.

Laboratory study of the atmospheric heterogeneous oxidation of benzo[a]pyrene
… of particle-phase benzo[a]pyrene (BaP) with atmospheric oxidants ozone (O₃) and hydroxyl radical (OH) was investigated by simulating atmospheric conditions in a laboratory environmental chamber and measuring the particle-phase species with an Aerodyne Mass Spectrometer (AMS). Kinetic …

Mesometeorological modelling and trajectory studies during an air pollution episode in the lower Fraser Valley, British Columbia, Canada
… in the LFV, this study employed the Regional Atmospheric Modelling System from Colorado State University, a non hydrostatic, three-dimensional mesoscale modelling system to simulate the detailed structure of air flows over the valley for one specific episode day. Significant code modifications …

Science to support toxics governance : tracking mercury and other pollutants from policy to impacts
… use interdisciplinary tools and approaches-from atmospheric modelling to community engaged research-to better trace this path from policy to human impacts, in support of environmental decision-making at multiple levels of governance. Combining simulation modelling, statistical, and qualitative …

An Investigation of Local and Regionally Significant Non-Agricultural Sources of Ammonia in Toronto and the Great Lakes Region
Atmospheric ammonia is a significant environmental pollutant that contributes both to human mortality and morbidity and can also negatively influence ecosystem health. While the globally dominant source of ammonia pollution is agriculture, other sources may be influential on local and regional …

Investigating the Characteristics of Exoplanetary Atmospheres and Interiors
… such as mass and radius combining with detailed atmospheric spectroscopy to provide unprecedented insight into the nature of these remote worlds. However, these high-quality observations also require sophisticated modelling and analysis tools in order to maximise the scientific output from the …

Wind and temperature in a glacierised Himalayan valley, and their controlling mechanisms
… of in-situ measurements and fine-scale numerical modelling studies, important factors influencing melt and precipitation, such as the local valley wind regimes and the lapse rates of near-surface temperatures, are poorly understood in the HKKH. This thesis aims to improve understanding of the …

Chemistry-climate modelling studies of decadal and interdecadal variability in stratospheric ozone and climate: The 11-year solar cycle and future ozone recovery
… model to explore several aspects relating to the atmospheric response to the 11-year solar cycle forcing and future stratospheric ozone recovery. Firstly, following recent improvements in the model, the atmospheric response to the solar cycle forcing simulated in UMUKCA is discussed. It is shown …

Unstetige Galerkin-Diskretisierung niedriger Ordnung in einem atmosphärischen Multiskalenmodell
Die Dynamik der Atmosphäre der Erde umfasst einen Bereich von mikrophysikalischer Turbulenz über konvektive Prozesse und Wolkenbildung bis zu planetaren Wellenmustern. Für Wettervorhersage und zur Betrachtung des Klimas über Jahrzehnte und Jahrhunderte ist diese Gegenstand der Modellierung mit …

Atmospheric implications of untested carbonyl photochemistry: an evaluation using chemically explicit and global 3D modelling
… the carbonyl group (C=O) are some of the most atmospherically important. While all organic species react with OH and other radicals, the C=O bond in carbonyls provides a chromophore for photolysis reactions. Consequently, carbonyls react quickly and are an important source of atmospheric …
