Abstract
This paper aims to investigate the utilization of the
Synthetic Storm Technique to convert rain rate time series to
rain attenuation time series using the ITU-R P.839, Stutzman and
Bryant rain height models. Furthermore, the study aims to
compare the actual rain attenuation with that predicted by the
SST using the three above-mentioned rain height models based
on rain rate and rain attenuation both measured concurrently.
The reason for conducting this study is the fact that previous
studies found that SST derived attenuation using the ITU-R
P.839 rain height model is close to measured attenuation in low
rain intensity but it is overestimated in medium rainfall and
extremely overestimated in high rainfall rate. Therefore, it is
vital to investigate the utilization of the SST using two additional
rain height models which are the Stutzman and Bryant models.
The study relies on rain rate time series and rain attenuation
time series measured at University Science Malaysia (USM)
campus (4.390 N, 100.980 E). The study found that the higher the
rain rate, the higher is the percentage error for the SST
predicated rain attenuation using the three above-mentioned rain
height models as compared with measured rain attenuation.
However, it is observed that when the Stutzman model applied as
part of the SST model, the prediction is more accurate of the
three rain height models.
