AbstractIn 2001, Leonids meteor shower was expected the impressive appearence would be seen.It was very important to monitor and catch the Leonids meteor activity at all times. Radio MeteorObservation is one of the best method for monitoring meteor activity. Because it is possible toobserve at all times even if in bad weather and at twilight time. In addition, by unifying worldwidedata, the radiant elevation problem can be solved. In this research, the Leonids active structureand characters are made clear by using worldwide data. These data were provided by the globalproject of Radio Meteor Observaiton. This project participants were 91 observing sites in 15countries. As a result, the high activity kept for 17 hours since 6:OOUT 18th. The half width timeof the first peak (America) was three hours and the main peak (Asia and Australia) was 10 hours.In addition, from Japanese data, we found the complicated peak structure. The Asian peak wasmade up of three types. They were main peak around 18:30UT, sub peak arotind 21:30UT andbright meteors compornent.
