Abstract
Malaysia is well known for its wet tropical climate and monsoon seasons which bring rainfall almost throughout the year. Therefore, designing wireless communication links above 10 GHz for Malaysian weather involves study of rainfall rate and its integration time. The knowledge of local 1-min rainfall rate statistic is the key input for the estimation of signal attenuation due to rain. Due to limitation of 1-min rain rate data availability, the conversion model is necessary to translate higher integration time rainfall rate to the required 1-min rainfall statistic. In this paper, rainfall data from six locations in the East Malaysia is acquired from a local hydrological agency and processed to a meaningful 1-min, 5-min and 10-min rainfall rate statistics. Then, four conversion models are used to convert from 5-min and 10-min rainfall rate to 1-min rainfall rate. From the conversion error analysis, it is found that the Emiliani et al conversion method performed the best for this study.
