Rainfall structure top to bottom by radar (GPM)
What it measures. A vertical slice through precipitation, showing how rain and snow are structured from the cloud top down to the ground, along with estimated rain rates, sampled in 5 km footprints.
How it's made. Produced by the Dual-Frequency Precipitation Radar aboard the GPM Core satellite, which sends down two radar beams and reads the returns at each step along its path.
How & where you'd use it. Lets scientists see the inner workings of storms and verify rainfall estimates, improving how we measure and forecast precipitation worldwide.

Official description
Version 07 is the current version of the data set. Older versions will no longer be available and have been superseded by Version 07. . 2ADPR provides single- and dual-frequency-derived precipitation estimates from the Ku and Ka radars of the Dual-Frequency Precipitation Radar (DPR) on the core GPM spacecraft. The output consists of three main classes of precipitation products: those derived from the Ku-band frequency over a wide swath (245 km), those derived from the Ka-band frequency over a narrow swath (125 km), and those derived from the dual-frequency data over the narrow swath. The Ka-band results are further divided into the standard and high-sensitivity estimates. In the standard sensitivity mode, the fields of view within the inner swath are matched to those of the Ku-band. Data from these matched-beam Ku- and Ka-band fields of view are used to derive the dual-frequency precipitation products. The retrievals are performed at each radar range bin along the slant path of the radar instrument field of view (IFOV).
