Characteristics of pollutants and their correlation to meteorological conditions in Hungary applying regression analysis

Abstract

Air pollution occurs when harmful or excessive quantities of substances including gases, solid particulates, and biological molecules are introduced into the atmosphere. The analysis of the relationship between air pollutants and meteorological factors can provide important information about air pollution. The aim of this study is to examine and explore the relationship between the different monitored air pollutant concentrations such as carbon-monoxide (CO), nitrogen-oxides (NOx), ozone (O3), particulate matter (PM10), and sulphur-dioxide (SO2) and the selected meteorological factors such as wind speed, temperature, precipitation, and atmospheric pressure. The investigation is based on data observed during a 10-year-long measurement period (2004–2014) in the city of Veszprem located in the western part of Hungary, in the Transdanubia region. In the present research, regression analysis was the chosen statistical tool for the investigation. The analysis found that there is a moderate or a weak relation between the air pollutant concentrations and the meteorological factors.
