Parametrized eXtreme Rainfall (PXR)

Courty, Laurent G.; Wilby, Robert L.; Hillier, John K.; Slater, Louise J.

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.
