The merit of the ground-based observations is that high sensitivity antenna and high time resolution receiver can be employed without limitations of the equipment mass and downlink data rate, which often becomes issues in spacecraft observations. On the other hand, the demerit of the ground-based observation with single station is coverage: The ground station can not observe Jovian radio emission while the Jupiter is below the horizon. However, this demerit can be solved by combining datasets from multiple stations. Virtual Observatory (VO) could be a promising solution for such combined data analyses.
Wideband radio wave observation has been performed at Iitate station since 2000. The wideband radio spectrograms since 2004 have been already archived in CDF format. In addition, the metadata of them has been developed through the Inter-university Upper atmosphere Global Observation NETwork (IUGONET) project. They could be adapted to VO with a little modification. In the presentation, we will show the current status of the Iitate data archive and combined analysis results with Nancay Decametric Array (NDA) data as a sample use case.
