Ranking of the Iberian Peninsula daily precipitation

What is it about?

A new method for ranking daily precipitation events is presented based on daily gridded precipitation. The magnitude of an extreme precipitation event is obtained after considering the area affected as well as its intensity in every grid point and taking into account the daily normalized departure from climatology. Different precipitation rankings are presented considering several domains.

Why is it important?

In this work EPEs rankings are established independently from the occurrence of significant socioeconomic impacts. The events are characterized by daily high-precipitation sums that influence relatively large areas. It should be stressed out that the method can be easily adapted to find cases that are more intense and/or more localized. For that the std threshold should be tuned to higher values (e.g. 3 or 4 std) in order to restrict the anomalous precipitation over localized areas. Finally, it it is worth mentioning that the method may be replicated to other regions where gridded precipitation is available.
