Short description

Mission statement

The goal of this program is to develop scientific skills necessary to identify and analyze environmental issues. Students will learn critical thinking, problem solving and skeptical inquiry skills and use them to propose solutions to environmental problems.

This program is recommended to applicants who have a solid interest in environmental problems, and has not yet decided her/his specified field of scientific orientation and depending on her/his interest and background knowledge, projects can be shifted to different directions because of their open structure and flexible organization.

This program enables students to join the work of internationally respected research groups. We offer training in up-to-date experimental methods and field exercises besides the solid theoretical background education.

Strength of program

The Doctoral School offers specialized training in the following directions in environmental sciences: environmental biology, environmental chemistry, environmental physics, or environmental geosciences. Emphasis is on the application of the given discipline in complex research projects, such as water quality changes and management, risk analysis and mitigation in various human and natural environments, renewable energy research, etc.

Meteorological modeling of the land-surface–atmosphere interactions: a historical review

Short description of Course: The land-surface (non-vegetated and vegetation-covered surface) and the atmosphere are always interacting.

The interaction could be investigated on macroscale (climatological applications) by running coupled GCM(Global Circulation Models)/SVAT model system to get insight into land-surface modulating effects of climate and vice versa. The interaction could also be investigated at smaller scales, for instance, at scales of weather events by running coupled

  • Planning: deciding the subject of the paper (question of originality); choosing the target journal (topics and impact factor); deciding the form of the paper (types of scientific papers).

  • Writing the paper: collecting material (how to use laboratory notes); writing the first draft (literature, most important results, final conclusion); obtaining instructions for the authors; designing tables, figures and other illustrations, copyright questions; how to write the chapters of a paper: Abstract, Introduction, Material and methods, Results, Discussion (their structures, specialities, grammar, expression to avoid); Reference list, Acknowledgements (contribution, technical assistance, financial support); deciding the final title, the running title, the keywords, and the

Transboundary environmental impacts and the international environmental cooperation

The international environmental scientific and policymaking collaboration have rapidly boosted since the 1970s thanks to the gradually improved observations and enhanced research activities. There is already a comprehensive system of international cooperation that addresses the transboundary and the global environmental problems which include a multitude of institutions, fora, programmes and agreements. Proper understanding of the interrelations and interactions of the scientific and policymaking processes is need for the sake of the development of the adequate responses for the solution of the respective environmental problems and also for the identification of those issues where further research is necessary. After demonstrating the historical development of this cooperation

Data analysis in environmental science

Goals of the course:
• To give an introduction into R, a freely available statistical and computational environment, which is widely used by scientists all over the world.
• To change the perspective of the students on statistics. In particular that data are realizations of random variables and thus descriptive statistics, which depend on the data, are also random variables.
Syllabus:
Introduction to R, in particular its basic commands, possibilities for reading in data, storing and preprocessing them, basics of graphical tools. The subsequent goal is to introduce and apply univariate data analysis methods in R covering the following topics:
- statistical sample, basic statistics
-requirements of estimation
-histograms, distributions and their assessment

How to measure size and shape of nano- and micro size particles?

Laser diffraction is a well known technique for characterizing particles of sediments/powders but other techniques are also available. First part of the course focuses on the difficulties of the laser diffraction (e.g differences of optical systems, Fraunhoffer vs Mie theory, polydispersity, etc…), second part introduces alternative options for particle characterization: light scattering and static optical particle shape analysis.

Scale dependent atmospheric dispersion models

After the review of basic concepts of the meteorology and air quality modelling we analyse the hydro-thermodynamic equation system of atmosphere and air pollution transport equation. We’ll study the structure of atmospheric turbulence, concern with various order closure hypotheses. We’ll review the classification of the dispersion models (statistic and dynamic, Lagrange and Euler types, etc.). Construction of local and mesoscale air pollution and PBL models are also investigated. Air pollution model applications in Hungary especially in the Hungarian Meteorological Service will be investigated in the end of the course.

International conventions on environmental protection and nature conservation

The international conventions were elaborated on those environmental problems which had been identified by the research community by means of environmental observations, analytic methods and models, and which could only be solved by the commitments of all those countries that were responsible for those problems and/or suffered from their adverse impacts. The subjects of the multilateral environmental agreements (MEAs) cover almost all components of the global environment and their large-scale processes. The lectures of this course demonstrate the essence of the most important agreements on environmental elements (atmosphere, transboundary water bodies, biosphere etc.), on human activities influencing the environment and their impacts (through the emission of pollutants,
