Study of effective path length and path reduction factor over some stations in India

摘要

Path reduction factor and effective path length, the two factors necessary to predict attenuation of millimetre waves by rain have been estimated for ten stations in India by using rain rate data obtained from India Meteorological Department. Cumulative distributions and variations of these two factors with rain rate have been deduced. The power law relations have been derived relating these two parameters with rain rate and percentage of time.
