Abstract :
The rain attenuation and attenuation distribution have been obtained using the measured rain drop size distribution (DSD) and the ITU-R model of rain rate distribution over the frequency range of 10-200 GHz at three locations in the Indian region, to indicate the variability in the rain attenuation pattern in the tropical region. The prevailing DSD in the tropical region can cause very significant variability in the rain attenuation distribution indicating the need for long term and extensive measurement of DSD in the tropical region.
