  "x_description": "This dataset contains the geographic latitude and longitude of the footprints of the C3 spacecraft,\non the altitude of 120 km above the Earth surface, based on T96 magnetic field model (Tsyganenko 1996).\nThe input parameters to T96 are based on the relevant solar wind and geomagnetic parameters taken\nfrom the OMNI dataset. Quality flags for\nthe ionospheric mapping and Solar Wind data are given as well. Also, a distance between the spacecraft C3\nand a model magnetopause as well as GSE coordinates of the spacecraft are provided.\nThis dataset also gives magnetic field components in GSE coordinates, predicted from the T96 model.\n\nThis dataset was generated as part of European Union ECLAT project. The aim of the European\nCluster Assimilation Technology (ECLAT) is to provide a novel data base, by providing an upgrade\nto the CAA. To achieve this , ECLAT programme ingests into the CAA supporting data from other\nspace- and ground-based observatories, provide data mining routines, refine data products and\nsoftware tools for their visualisation, and develop existing European magnetospheric modeling\ninfrastructure to provide context for the observational data.\n\nThe contacts for the ECLAT project are\nSteve Milan, University of Leicester\nRumi Nakamura, Oesterreichische Akademie der Wissenschaften\nKirsti Kauristie, Finnish Meterological Institute\nVictor Sergeev, Petersburg State University\nHermann Opgenoorth, Swedish Institute of Space Physics",
