PPDIST
Precipitation Probability DISTribution
Overview
The Probability DISTribution (PPDIST) dataset represents a collection of global high-resolution (0.1°) observation-based climatologies (1979–2018) of the occurrence and peak intensity of precipitation at daily and 3‑hourly time scales.
The climatologies were produced using neural network ensembles and take advantage of the strengths of all three main precipitation data sources — satellites, reanalyses, and gauges — to obtain reliable estimates for the entire globe. For more information, see the following open-access paper:
