Abstract:
To promote interdisciplinary studies of solar-terrestrial physics with different types of observation data, the Inter-university Upper atmosphere Global Observation NETwork (IUGONET) project started in 2009, participating in five institutes (Tohoku University, National Institute of Polar Research, Nagoya University, Kyoto University, and Kyushu University). In this project, we have added data information (metadata) for various kinds of ground-based observation data in the solar-terrestrial physics and built a practical database (IUGONET Type-A) to share them on the Internet. We have also developed an integrated data analysis tool (IUGONET Data Analysis Software: UDAS) written in an Interactive Data Language (IDL). This analysis tool is a plugin software for Space Physics Environment Data Analysis Software (SPEDAS) to analyze and visualize various kinds of observation data. In the IUGONET Type-A, users can easily learn characteristics of observation data through the quick look images/plots and how to use several basic commands to visualize the data. Recently, we updated Space Physics Archive Search and Extract (SPASE) metadata schema from 2.2.6 to 2.4.0 so that we can describe a Digital Object Identifier (DOI) and Open Researcher and Contributor ID (ORCID) in the IUGONET metadata. In order to enhance an international use of these IUGONET products and to promote interdisciplinary studies of solar-terrestrial physics, we have held tutorial seminars and workshops several times in both Japan and foreign countries. Through these activities, many scientific papers and Master/Doctor theses have been published by using an analysis environment. These facts prove that the IUGONET products effectively work as an international platform.
