dc.description.abstractData from NASA TRMM satellite and rain gauges, the rain rate per hour was studied. The comparison took place in San Juan, Puerto Rico; when the Tropical Storm Jeanne passed over the island of Puerto Rico. Natural variations in raindrop size distribution (DSD) were studied for X band radar from October 2004 to July 2005 and September 15 to 16 , 2004 in San Juan, Puerto Rico. Three types of estimators of rain rates were examined: A classical estimator R(ZH) and two polarimetric radar estimators R(KDP) and R(ZH,ZDR) . According to simulation results, the normalized errors (NEs) with respect data disdrometer of R(ZH),R(KDP) and R(ZH,ZDR) for all DSD samples in October 2004 to July 2005 data are 40.85%, 14.73%, and 15.83% respectively, while for the tropical storm Jeanne they are 23.39%, 9.35% and 14.53%. The results show that the estimator R(ZH) is the most sensitive to variations in DSD.en_US
