We introduce activities to provide infrastructure and opportunity for upper atmospheric research and to promote interdisciplinary study, which have been made by Inter-university Upper atmosphere Global Observation NETwork (IUGONET) project. IUGONET is a Japanese inter-university project, which was established in 2009 by Tohoku University, Nagoya University, Kyoto University, Kyushu University, and National Institute of Polar Research to develop the infrastructure for sharing their upper atmospheric data, including solar and planetary data (Hayashi et al., 2013).

We have developed two tools, i.e., a metadata database and an analysis software for the upper atmospheric data (Tanaka et al., 2013; Abe et al., 2014). The metadata database enables users to cross-search various kinds of the upper atmospheric data distributed across the IUGONET members. A new metadata database, IUGONET Type-A, which was released in November 2016, provides one-stop services such as searching data, showing information of the data (i.e., metadata and quick-look plot of the data), finding interesting phenomena, interactively visualizing the data, and leading users to more detailed data analysis by using a dedicated analysis software, Space Physics Environment Data Analysis Software (SPEDAS). SPEDAS is a grass-roots software that was written by Interactive Data Language (IDL) and was developed by scientists and programmers of the Space Sciences Laboratory at the UC Berkeley, the Institute of Geophysics and Planetary Physics (IGPP) at UCLA and other contributors. It is capable of dealing with data from multiple satellite and ground-based missions. We have provided a plug-in software for SPEDAS, which allows users to analyze the data obtained by the IUGONET members with various instruments, such as solar telescope, ionospheric and atmospheric radars, imagers, riometers, magnetometers, and so on. In addition, we hold data analysis workshops to explain how to use these IUGONET tools and data in Japan and sometimes foreign countries several times a year. In particular, we are planning to have workshops in Nigeria, Africa, and Indonesia, South East Asia in FY2017, in collaboration with a project of the Core-to-Core Program of the Japan Society for the Promotion of Science (JSPS), “Study of GNSS satellite anomaly in the Asian and African equatorial region”. We believe that the IUGONET tools should be useful for the capacity building in Asia and Africa.
