Parametrized eXtreme Rainfall (PXR)

Parametrized eXtreme Rain (PXR) is a dataset that simplifies the representation of extreme precipitation on a global scale. It allows the creation of Itensity-Duration-Frequency (IDF) curves. PXR are created by fitting the extreme value distribution on the annual precipitation maxima obtained by reanalysis. PXR-2 consists of maps of the Gumbel parameters for 19 event durations (1 to 360 hours). PXR-4 uses the scaling characteristic of the distribution parameters to provide a simpler, four-parameter dataset that could be employed to create IDF curves for a range of durations
