Homogenization of precipitation data in Pannonian region

Abstract

Testing the homogeneity of data of meteorological occurrences is very important for ensuring the reliability and accuracy of the data that will later be used in a variety of research related to the assessment and prediction of future trends of climate changes. This paper presents the verification of homogeneity of data on average annual precipitations from 19 meteorological stations in the Pannonian region. For this purpose, it has been used four different statistical tests that are applied on each meteorological station individually. It was found that 4 out of 19 meteorological stations or in 21% of the cases there are in homogeneities of precipitation data.
