Abstract

This paper describes the measurement of zenith path attenuation due to rain in winter and monsoon seasons of the year 2001 at Amritsar (31° 38' N 74° 52' E) India, using zenith looking radiometer operating at 19.9 GHz frequency. The effective rain height has been obtained from the analysis of the radiometric data and point rainfall intensity. Specific attenuation for various rain rates in the present study has been evaluated from measured drop size data using lognormal drop size distribution. The average effective rain height at Amritsar has been estimated to be 3.4 km, and compared with that of predicted by ITU-R.
