Extreme precipitation events are rare, but they are very important in the global hydrological cycle. Accordingly, it is important to be able to characterize their distribution, frequencies, and magnitudes. Liu and Zipser report observations recovered over a full year by instruments on the Global Precipitation Mission Core Observatory satellite, which provide diurnal three-dimensional coverage of the entire subpolar world and categorize precipitation events by their area, depth, and convective intensity. These types of events are important to include in global climate models, in order for them to accurately describe the global water cycle.
