| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | Rain attenuation statistics are obtained for both up and down links of Ku-band Superbird C, which connects the earth stations at Equatorial Atmosphere Radar (EAR) in West Sumatra, Indonesia and Research Institute of Sustainable Humanosphere (RISH) of Kyoto University in Uji, Kyoto during four years from Sept.2002 to Sept.2006. The rain attenuation and its annual statistics are simultaneously calculated from the precipitation cloud echoes measured by the X-band meteorological radar, being in good agreement with the direct measurements by the satellite signals. The radar observations also indicate the decrease of time percentages in high attenuation range due to localized structure of the clouds. The duration time of rain attenuation is estimated from the horizontal distribution and moving speed of the X-band radar echoes. It is found that some of the duration time can be much longer than in Japan even for extremely large rainfall rate exceeding 50 mm/h. | |
