The National Space Development Agency of Japan (NASDA), the
Communications Research Laboratory (CRL) and the National Aeronautics
and Space Administration (NASA) will have the symposium on the Global
Precipitation Measurement (GPM) on November 9 (Friday).

GPM is a follow-on and expanded mission of the current on-going
Tropical Rainfall Measuring Mission (TRMM). It is a earth observation
satellite program for the expansion of observing areas (from the
tropical to the global area), the improvement of observing frequency
(drafting an global precipitation map in every three hours) and the
enhancement of measuring methods (identifying rain and snow using the
dual-frequency precipitation radar (DPR) and improving a rainfall
estimation). The data acquired by GPM is expected to be useful for
monitoring and predicting meteorological changes including global
warming in the long term, and for responding to social needs such as
weather forecast, water resource management in the short term.

This symposium is held at 13:30 at Chiyoda Hoso Kaikan (Tokyo) to
develop GPM’s objectives and missions and to enhance public
understanding of its expected results.
Those who are interested in the Symposium are all welcomed and contact
us for more information.
