Scan pattern change of the Ka-band Precipitation Radar (KaPR)
JAXA and NASA changed the scan pattern of Ka-band precipitation radar (KaPR) on May 21, 2018, after transition to latter phase in operation. Before this scan pattern change, dual-frequency information by Ku- and Ka-band radars could observe precipitation only in a narrow inner swath of 125 km, whereas dual-frequency observation information can be applied in full swath of approximately 255 km after the pattern change. By applying the algorithm corresponding to the scan pattern change, new GPM/DPR product can obtain dual-frequency information in full swath of 255 km.

GPM Orbit Boost
The GPM Core Observatory satellite performed two orbit boost maneuvers on Nov. 7 and 8, 2023 that raised its altitude from 407km to 442km.
