[MGI27-05] Development status of the metadata server and data archives at Tohoku University for collaborative studies using planetary radio and spectroscopic data
Keywords:Jovian DAM, IUGONET, Europlanet/VESPA
Ground-based observations with multi-longitudinal stations enable us 24-hour continuous track of the activity variation of the Jovian auroral radio emissions. By using Spectrograms of Jovian decametric radiation obtained at Nancay and Iitate observatories, and spectroscopic data from Hisaki spacecraft, we are performing analyses of the effects of the Io's volcanic activity in 2015 on the occurrence timing of the arc structures in the spectrogram of Jovian decametric radiations. Source identification method of the Jovian decametric radiation was developed based on Nancay data [Marques et al., 2016]. We are going to apply the method to dataset including Iitate data, and utilize for statistical analyses. Another merit of the ground-based observations is that we can use facilities such as large antenna array, high time/frequency resolution receivers, high-speed networks, and large amount storages, which are difficult to use in the spacecraft observations. We participate Juno ground support team and exchange the information on support observation schedules.
