    The Exploration of energization and Radiation in Geospace project Science Center (ERG-SC) has developed the science data file archive and integrated data analysis tool for the ground network observation data of the ERG project. We have organized data design consortiums to develop and elaborate the standard metadata and data variable sets for each type of the ERG-related ground data being archived as Common Data Format (CDF) files. The integrated data analysis software for the project has also been developed on the basis of the Space Physics Environment Data Analysis Software (SPEDAS) which works in concert with the CDF data file repository. The software tools, which are provided as plug-in libraries for SPEDAS, are made available to the international science community so that scientists and students are ready to proceed to integrated studies combining the ground data with other satellite and simulation data seamlessly. The integrated data analysis software can make scientific activities more productive and help the ERG project achieve the scientific goals.

    In order to understand the mechanism of global-scale phenomena in the upper atmosphere, multidisciplinary researches using many kinds of data are important. An infrastructure to access to many kinds of data on the Internet is one of the keys to the multidisciplinary researches. The Inter-university Upper atmosphere Global Observation NETwork (IUGONET) project solved this problem by developing a metadata database to provide information such as URL of database or each data .le, which are managed dispersively by several institutes. Because the metadata database covers a wide scienti.c .eld, it is likely that non-specialized users can not easily select a right search phrase. We connected an associative search engine which is called GETAssoc with the metadata database, in order to get the related words and to generate re-query phrases by using them automatically. We collected metadata from SAO/NASA Astrophysics Data System to create the dictionary for associative search. We show that the prepared dictionary gives the related terms as expected for generating re-query phrases.

    This paper reports on the benchmark test of the metadata management system developed by the Inter-university Upper atmosphere Global Observation NETwork (IUGONET) project. The IUGONET metadata management system consists of the metadata reception module based on file repositories of Git, which is a widely-used version control software, and the metadata import module to register metadata to the metadata database using the DSpace commands. We made the performance assessments for these two modules in terms of the processing speed for registering/importing metadata both on a native Linux platform and a virtualized Linux platform. As a result, the metadata reception module processes properly eve millions of registered metadata within several minutes at most, showing roughly the similar performance for the native and virtualized platform. On the other hand, the metadata import module needs much longer processing times of several to a few tens of hours for the same amount of metadata. As compared with the virtualized platform, the native platform gives a four times faster speed for updating indices for the built-in search engine based on Lucene. From a perspective of the regular operation of the metadata management system, the metadata import module runs more efficiently on the native Linux platform and it is estimated by our performance test that it takes about 5 hours to newly import 105 metadata files and subsequently takes about 21 hours to update the Lucene indices for the registered metadata of 5 × 106 in total.

    In the IUGONET (Inter-university Upper atmosphere Global Observation NETwork) project, we have developed UDAS (iUgonet Data Analysis Software), which is a software to visualize and analyze various kinds of upper atmospheric data distributed by five universities/institutes (Tohoku Univ., Nagoya Univ., Kyoto Univ., Kyushu Univ., and NIPR). UDAS is a plug-in software of TDAS (THEMIS Data Analysis Software suite) written in IDL (Interactive Data Language), and thus can call useful routines to visualize and analyze time series data and GUI included in TDAS. We released a beta version of UDAS at the IUGONET website in May, 2011, and a formal version in February, 2012. We are planning to incorporate UDAS into TDAS and release it from the THEMIS software website after September, 2012. Automatic test tools for the UDAS programs were developed to reduce the workload for the development team. Furthermore, we built an executable file of TDAS that can run on the IDL Virtual Machine environment without any IDL licenses and released it for public testing. These developments will contribute to the promotion of the use of the UDAS and the ground-based observational data distributed by the IUGONET institutions.

    We have developed European incoherent scatter (EISCAT) database which contains ionospheric parameters (electron density, electron and ion temperatures, and ion velocity) measured with EISCAT radars located in northern Scandinavia and Svalbard. The EISCAT database provides valuable information for studies on upper atmospheric physics in the polar region. In addition, combinations of the EISCAT database and other in-situ and ground-based databases are essential to understand dynamics of the interaction between polar mesosphere, thermosphere, ionosphere, and magnetosphere. In this paper, we explain the current status of data analysis and visualization of the EISCAT database, and discuss their application to a next generation imaging radar project named EISCAT_3D.

The IUGONET common metadata format has been designed on the basis of the Space Physics Archive Search and Extract (SPASE) data model/metadata format, which has been developed by the SPASE consortium, with some modifications made by IUGONET to accommodate metadata for the various kinds of ground observational data produced by the IUGONET institutes and universities. We have also developed the registration/management system for metadata XML files using GIT, which is a widely-used version control software. With the designed metadata format and the metadata management system, IUGONET continues to generate and archive metadata for the observational data of Japanese Solar-Terrestrial physics community.

    This paper describes an overview of the Inter-university Upper atmosphere Global Observation NETwork (IUGONET) project and briefly mentions important products to be developed in the project. It is an inter-university program by the National Institute of Polar Research, Tohoku University, Nagoya University, Kyoto University, and Kyushu University to build a database of metadata for ground-based observations of the upper atmosphere. The metadata database will be of great help to researchers in efficiently finding and obtaining observational data spread over the universities and institutes. This should also facilitate synthetic analysis of multi-disciplinary data, which will lead to new types of research in the upper atmosphere. The IUGONET development team designs its metadata format based on the SPASE (Space Physics Archive Search and Extract) data model. Some modifications depending on characteristics of ground-based observations of the upper atmosphere are added. The metadata database system is built on the platform of DSpace with customizations according to the IUGONET metadata. In addition, an analysis software for the observational data provided by the IUGONET institutions is developed based on the TDAS (THEMIS Data Analysis Software suite) library written in IDL (Interactive Data Language).

    We have been building the metadata database of the gound-based observational data for upper atmosphere as developers of the Inter-university Uppear atmosphere Global Observation NETwork (IUGONET) project which is a six year research project from fiscal 2009 by the five Japanese universities and institutes. The main purpose of the metadata database to facilitate access is the improvement of accessibility to the various kinds of the observational data which are distributed to many databases in the various institutes. We designed the IUGONET common metadata format which is based on the SPASE data model/metadata format developed by the SPASE Consortium. Then we customized DSpace, a free repository software, which handles the Dublin Core metadata format by default, to handle the IUGONET common metadata. In this paper, we describe the IUGONET metadata database as a case example of metadata database adaptation for geoscience.
