Abstract: We present a novel web browser based interactive visualization application for exploring 3D weather radar data sets delivered by next generation phased array radars. The purpose is to aid in rapid observation of localized weather phenomenon, short term weather forecasting and disaster prevention. Our application allows remote users to access multiple data sets via a web browser application, and the ability to view ray casted weather data volumes atop 3D maps from different viewpoints, animated in time. The interface allows updating intensity threshold and color scale range for comprehending 3D precipitation shape at different intensity levels, vertical cross-sectional views for viewing the internal structure and orthographic projection onto 3D map to clearly locate the affected areas. A demo collated using Osaka city torrential rain data set was presented to domain experts and received encouraging remarks on usability and performance.
