Abstract
Access to climatic data is a fundamental prerequisite in any climatic study. In past years, data received from Meteorology organization stations were among the most reliable and acceptable data for climatic study and using precipitation data of these stations were a dominant paradigm among climatologists. But in recent decades, flaws and incapability of this paradigm in generalizing data received from one station to a zone especially in the case of unruly variables like precipitation resulted in adding a new paradigm and applying precipitation network data. Needs of the new paradigm to these kinds of data are somehow satisfied with precipitation network data.
These bases collect precipitation data from different resources and produce these network data in different degrees of separation using specific geo-referenced methods for regional to global zones in long time periods. However, complete analysis of each available station is not possible due to multiple and varied available versions. The present article seeks to introduce the overall structure and general features of precipitation network data bases and their capabilities. Finally, precipitation map was produced based on data received from some precipitation data stations.
