Abstract EN

In this study a homogeneity test was performed for 18 stations with respect to annual precipitation from 19601961/ to 20092010/ along Syria.

Four methods, namely Standard Normal Homogeneity Test (SNHT), Buishand range test, Pettitt test, and Von Neumann ratio tests were chosen to detect the homogeneity of the annual rainfall data with at most 5%missing values.

The results of the tests showed that 3 out of 18 stations can be considered heterogeneous and considered as “doubtful”.

The change points of these 3 stations were found to be significant at 5% level by two tests.

Therefore, it can be concluded that analyzing the homogenization and completing the missing data are essential for ensuring the reliability and suitability of long-term time series for studies on climatic changes and variations.
