A statistical probe into variability within total ozone time series over Arosa, Switzerland (9.68°E, 46.78°N)

Endeavor of the present paper is to investigate the statistical properties of the total ozone concentration time series over Arosa, Switzerland (9.68°E, 46.78°N). For this purpose, different statistical data analysis procedures have been employed for analyzing the mean monthly total ozone concentration data, collected over a period of 40 years (1932–1971), at the above location. Based on the computations on the available data set, the study reports different degrees of variations in different months. The month of July is reported as the month of lowest variability. April and May are found to be the most correlated months with respect to total ozone concentration.
