Popis:	Even identical rainfall intensity witl different distribution of rain drops diameters can result in different received power by rader, so it is difficult to determine precise rainfall intensity for all types of rainfall from received power by radar. In addition, because a radar beam passes 500-3, 000M Above ground level, rainfall intensity obsevred by radar does not necessarily coincide with the ground rainfall intensity. In thie paper the authers discussed the method of improving coherency between the current scene of a radar raingauge and ground rainfall by uaing past observed data of a radar raingauge and ground raingauges, and could find techniques yielding a certain degree of success.
