Global impacts of aircraft emissions on air quality and nitrogen deposition

Global passenger air traffic has doubled in the 13 years prior to 2019, and is expected to double again over the next 20 years or so. Growing demand for aviation is met by a corresponding increase in jet fuel being burned by aircraft, releasing multiple pollutants into the atmosphere. Besides disturbing the Earth’s radiative balance, these...

Biomonitor-Reflection of Large-Distance Air Mass Transported Trace Elements

The present thesis’ topic is the biomonitoring of atmospheric trace elements with attention focused on the long-range transported trace elements. The aim was to provide improved understanding of aerosol characteristics under the atmospheric transport dynamics of Central North Atlantic at different altitudes, and also evaluate the usability of...

Elderly Exposure to Air Pollutants: Measuring, assessing and modelling

This Thesis focuses on the estimation of the human exposure to air pollutants, and gives special attention to one of the most susceptible groups in the general population - elders. To fulfil the goal the work was conducted following the risk assessment paradigm and, consequently, was divided into 5 tasks: 1) characterization of the indoor air...

Ensemble-based data assimilation schemes for atmospheric chemistry models

The atmosphere is a complex system which includes physical, chemical and biological processes. Many of these processes affecting the atmosphere are subject to various interactions and can be highly nonlinear. This complexity makes it necessary to apply computer models in order to understand the natural behavior of the atmosphere. In addition to...

Some properties of the Langevin model for dispersion

The Langevin Equation is used to describe dispersion of pollutants in the atmosphere. The theoretical background for the equation is discussed in length and a review on previous treatments and applications is given. It is shown that the Langevin equation can describe dispersion in complex circumstances. In particular the equation is applied to...
