Atmospheric Physics & Environmental Modelling

Perhaps the most important course I took while an undergraduate student at UMIST was called Human Uses of Energy. It was given by Professor Mike Rusbridge and I remember vividly how he presented empirical facts about the state of global energy use and provided estimates in BTUs of the potential for harnassing energy from different natural and man-made sources. When it came to deciding what to do for my PhD, alternative energy and, in particular, fusion won out over my second choice – atmospheric physics. Atmospheric physics fascinated me as for the first time in my life, I started to understand why it rains, why it snows and how lightning strikes. It was all thanks to a single lecture course on atmospheric physics at UMIST given by Dr Clive (“the thunderbird”) Saunders – who used to fly airplanes full of instrumentation directly at, and through thunderstorms! When I returned to research in 2003, I had the opportunity to work in the field of atmospheric physics in Thessaloniki, Greece and I have spent the last couple of years working with colleagues at the National Observatory of Athens developing models of global aerosol mixtures and data analysis techniques based on neural networks to exploit the global coverage provided by polar orbiting satellites to interpolate aerosol micro-physical and optical properties over regions where no ground stations exist. A big challenge continues to be the accurate sensing of air quality from space and I have been working with colleagues in the Laboratory of Atmospheric Physics of the Aristotle University of Thessaloniki to develop and analyze multivariate models and datasets of atmospheric ozone and UV-derived products for climate changes studies. In parallel, I have developed statistical models to retrieve surface solar irradiance spectra and a range of solar energy UV applications from geostationary satellite cloud products with colleagues in the SOLEA project. More recently, my focus is on the application of metrology to satellite measurements so as to try to understand how uncertainty propagates through to climate data records with colleagues in the Department of Meteorology of the University of Reading, working for the FIDUCEO project.
