Effects of wind velocity on slant path rain-attenuation for satellite application in Malaysia

Earth-to-satellite signals suffer by Earth׳s atmosphere especially by precipitations. It is more severe in tropical climate. A reliable technique named as synthetic storm technique (SST) was proposed to predict the effects of rain on slant path. SST model uses rainfall-rate time series, velocity of...
