The\nTRMM satellite survived 17 years a nd brought many fruitful scientific results. In particular\, 3D data obtai ned with the PR have expanded our knowledge of precipitation structure at various locations and climate regimes over the globe. The Dual-frequency P recipitation Radar (DPR) on the core satellite of the Global Precipitation Measurement (GPM) mission succeeds the PR’s legacy and continues to pro vide us with radar echoes of precipitation with higher sensitivity and bet ter accuracy than the PR.\n\nThe topic treats of the characteristics of th e PR and DPR and the rain retrieval algorithms for them. Because of the si ze constraints\, both PR and DPR use higher frequencies than general groun d-based weather radars. Since high-frequency electromagnetic waves suffer from attenuation due to precipitation itself\, the attenuation correction is essential in the retrieval algorithms. The surface reference technique (SRT)\, which uses the difference in the apparent surface echoes between t he raining area in question and non-raining areas\, give a reliable constr aint for the attenuation correction. However\, there are several other fac tors that are entangled in a complicated way to affect the attenuation. Th e talk mentioned some of these factors and other peculiarities of space-bo rne radar data\, as well as possible future radar for precipitation measur ements from space.\n\nDr. Iguchi is a fellow of IEEE and a member of the A merican Meteorological Society and the Meteorological Society of Japan. He received a Culture\, Sports\, Science and Technology Minister’s Award ( 2007)\, Maejima Hisoka Award (2012) and Horiuchi Award of the Meteorologic al Society of Japan (2015).
