[MGI27-P01] Development of tools for sharing and utilizing the upper atmospheric data
Keywords:upper atmospheric data, metadata, DOI, analysis tool
Inter-university Upper atmosphere Global Observation NETwork (IUGONET) is an inter-university project which aims to promote sharing and utilizing the upper atmospheric data distributed across Japanese universities and institutes. In the field of solar and space physics, the International Heliophysics Data Environment Alliance (IHDEA) has encouraged to standardize metadata, data formats, APIs, and tools in order to enable sharing of data and to enhance science. Based on the standards and services recommended by the IHDEA, we have developed various tools, such as metadata database and data analysis software. The IUGONET metadata was created based on the Space Physics Archive Search and Extract (SPASE) data model to ensure high interoperability with other heliophysics databases. Our web service "IUGONET Type-A" allows users to search, retrieve, and visualize the upper atmospheric data by using the metadata. The current IUGONET metadata is based on SPASE 2.4.0, and we plan to update the metadata to the latest version 2.6. The SPASE 2.6 enables to handle the simulation data, therefore, we will be able to create the metadata for our own simulation data and register them to the metadata database. In addition, we have begun developing a system that can assign DOIs by using the IUGONET metadata in collaboration with the National Institute of Information and Communications Technology (NICT). Since more than 1,200 metadata have already been registered to our metadata database, it will be possible to assign the DOIs to many datasets. Our data analysis software is based on Space Physics Environment Data Analysis Software (SPEDAS), which is a grass-roots data analysis software written in Interactive Data Language (IDL). We have provided the plug-in software for SPEDAS, which includes the functions for loading the IUGONET data. Recently, we are also developing a plug-in for the Python-based Space Physics Environment Data Analysis Software (PySPEDAS). The plug-in under development is available on the web and we hope to add it to PySPEDAS in the near future.
