Events Dataset for "Nightside Auroral Arcs near the Electron Isotropy Boundary: TRACERS-THEMIS-MetOp Observations"

This dataset contains spacecraft trajectories (TRACERS-2, THEMIS-A/D, and MetOp-C) for the four events (2026-01-25, 2026-02-19, 2026-02-27, 2026-03-12) presented in the study. For each event, three 2D energy–pitch angle cuts are provided at three reference MLAT's, along with parallel/perpendicular/antiparallel energy spectra from TRACERS-2 as functions of MLAT and energy. All files are in .txt format. In addition, the Hall and Pedersen conductivities calculated with TREx-ATM and shown in Figure 3b are also provided in the trex_sigma_500keV and trex_sigma_10keV files for the <500 keV and <10 keV calculations, respectively.
