Improvement of Accuracy in Radar Precipitation Gauge System by an Alliance between Tokyo and Neighboring Municipalities
“Tokyo Amesh”is real-time radar rain gauge system Bureau of Sewerage, Tokyo Metropolitan Government operates. The information is available on our network and internet. The data source of it is two X-band radars, Minato and Inagi. The radar can observe rainfall intensity at the smallest unit of 250m by 250m square mesh. Operators make the best of the information for the safest pump operation. No good solution has been given to “rainfall attenuation” and “bright band”, the inherent problems for X-band radar. Also, for changeable movement of rain clouds broader panorama vision has been in demand from a standpoint of preventive operation. With these needs, Tokyo worked on allying with neighboring municipalities to share rainfall information. Saitama Prefecture, Yokohama City and Kawasaki City. By integrating data from the four systems into one, with a new composition method a great progress has been attained to solve the problems.
