Raising number of researches dealt with precipitation properties especially after the recent advances in measurement techniques and devices. It is becoming essential to reach a common understanding of rain event when addressing the relation of rain p
roperties with different climate patterns and its influence on variety of human activities. The aim of this research is to present a suitable rain event definition that would serve future research in this field. Data was acquired in Freising south of Germany in the summer of 2009. Four event definitions were generated then compared according to rain properties obtained by the disdrometer and the rain gauge, These properties included event count per definition, mean event duration, mean event rain intensity, mean event rain amount, total rain amount and total number of drops. One definition proved to be more suitable than the others exploiting the disdrometer precession.
