Visualizing weather radar data from volcanic eruption clouds.

This paper is submitted to accompany the article "Analyses of three-dimensional weather radar data from volcanic eruption clouds" [1]; it describes three-dimensional (3D) visualizations of the Sakurajima volcanic eruption clouds and the weather radar data used for analyses, as well as their availability and downloading procedures. The radar data were acquired by an operational X-band weather radar located approximately 11 km south of the Showa vent of Sakurajima in Kagoshima, Japan. The original raw radar data are available from the "XRAIN Precipitation Original Data search and Download System", which is hosted on the website "Data Integration and Analysis System (DIAS)". Animated images of the radar data shown here, which provide a visual explanation of the temporal evolution and the inner structure of volcanic eruption clouds, were created using the program "Analysis Tools of Three-dimensional Weather Radar Data (AN3D)". The detailed methods of ANT3D are provided in the co-submitted article "Construction of three-dimensional weather radar data from volcanic eruption clouds" [2].
