TL;DR
This paper introduces a new dataset that labels the locations of Cluster satellites in Earth's magnetized environment, aiding in data analysis.
Contribution
The GRMB dataset provides continuous, manually validated labels for Cluster spacecraft positions across 15 geospace regions.
Findings
The GRMB dataset spans 15 geospace regions, validated over 7 years with reference data and physical properties.
Cluster satellites spent about 15% of their time in regions like the lobe, plasmasheet, and solar wind.
Abstract
The geometry of the terrestrial magnetized environment, or geospace, varies widely in space and time due to the Earth’s magnetic field interactions with the interplanetary medium. A spacecraft’s location in geospace is only approximately determined by its coordinates since the environment is inhomogeneous, with distinct physical processes occurring in different regions. Knowing the location in the geospace offers a strong support for data analysis. This paper introduces a new dataset, Geospace Region and Magnetospheric Boundary identification (GRMB), which provides labelled positions for each Cluster spacecraft over the whole mission, with respect to the local environment. This continuous labelling is based on manual selection, supported by browsing 44 different Cluster data products. The GRMB dataset includes 15 labels spanning from the plasmasphere to solar wind regions. Its…
