The present thesis acts from the ozone relations in Austria. To analyse this topic is one ozone episode from the year 2003 and 2015, by using the methods of the descriptive statistics to illustrate in view of the complicated data amount on the one hand, and on the other hand, the closing statistics around comparisons and trends, edited. The principal purpose of this work is dedicated to the analysis of the different ozone concentration courses at the respective measuring points concerning differentiated geographic circumstances. There are different results in urbane, suburbanen and ruralen areas achieved. The biggest difference in the course of the ozone concentration appears in the average day ozone concentration which is higher in rural areas on account of the inhibited reduction of the ozone during the night hours. Further is to be observed, that in middle- and high mountain positions the ozone concentration shows basically lower day variations. The difference between the measuring points Gerlitzen and Hochwurzen is extremely low. However, a clear difference is noticeable between the measuring points Hochgößnitz at 900 m and Tamsweg at 1025 m sea level. The ozone concentration at the measuring point Hochgößnitz shows clearly lower day variations, than at the measuring point Tamsweg. Another main focus of this work is about showing the dependence of the ozone concentration by the meteorological conditions. It becomes evidently, that for the creation of a high ozone concentration a high air temperature, a big daily total of the global radiation and subsequently low rel. air humidity are promotive. In view of the wind speed is no uniform connection is noticeable in these episodes.
