| Abstract | (in Japanese) | (See Japanese page) |
| (in English) | The long-term rain attenuation statistics of cumulative time percentages are obtained from Ku band satellite signal observations conducted in Osaka Electro-Communication University, Neyagawa, Osaka, from 1988 to 2016, and compared with the prediction models based on the ITU-R Recommendations . Although the long-term statistics reported earlier for about 20 years up to 2006 were in very good agreement with the recent ITU-R predictions obtained from the 0.01% rainfall rate, those calculated newly for 28 years including the last ten years are found to be slightly larger than the ITU-R predictions. The increases of the cumulative time percentages may result from recent tendencies that the occurrence of rain attenuation due to tropical-type rainfall such as shower and typhoon increases in summer time, and that the average ground temperature at rain time becomes higher by 1-2°primarily in summer time. New prediction models which take into account recent climate change and meteorological conditions will be expected in the near future. | |
