GPM/DPR L3 Spectral Latent Heating (1-Month,0.5deg)

GPM Core Satellite carries DPR and a GPM Microwave Imager (GMI). 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 satellite'.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 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 (78 and 152 mile) (245 km since May 21, 2018) 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.
