Product Summary

GPM/DPR/KuPR L2 Precipitation dataset is obtained from the DPR sensor onboard GPM and produced by the Japan Aerospace Exploration Agency (JAXA). GPM Core Satellite carries Dual-frequency Precipitation Radar (DPR) and a microwave radiometer.
Main purposes of the GPM are "Comprehension of horizontal and vertical structure of precipitation systems", "Acquisition of precipitation particles information" and "Improvement of accuracy of precipitation by constellation satellites".
GPM Core Satellite can observe the range from the south latitude about 65 degrees to the north latitude about 65 degrees, and flies Non-Sun-synchronous Circular Orbit at about the 407 km (442 km since Nov. 8, 2023) altitude. To keep the altitude, the Core Satellite does the orbit maintenance maneuver. The interval is about 7-10 days.
The swaths of DPR instrument are 125 and 245 km (245 km since May 21, 2018) (278 km since Nov. 8, 2023) for a Ka-band precipitation radar (KaPR) and a Ku-band precipitation radar (KuPR) respectively. In addition, simultaneous measurements are done at the overlapping of Ka/Ku-bands of the DPR. The GMI instrument is a conical-scanning multi-channel microwave radiometer covering a swath of 904 km (1015 km since Nov. 8, 2023).
The level 2 processing algorithm of the dual frequency precipitation radar additionally uses received power value profiles observed by KuPR and KaPR to estimate a precipitation intensity profile. It also estimates precipitation type, precipitation top height, and bright band height. Level 2 algorithm input data is a level 1 DPR product (calibrated radar echo power value profile), and level 2 algorithm output data is a level 2 product (precipitation intensity profile).
The provided format is HDF5. The Sampling resolution are 5km(horizontal) and 125m/250m(vertical). The current version of the product is Version 7. The Version 6 is also available. The generation unit is one orbit.
