2026-10-08 Queqiao-2 EUC payload observation dataset from February 24, 2025 (UT 11:08-16:18) doi:10.57760/sciencedb.39452 en This dataset contains observational data acquired by the Queqiao-2 satellite's EUC (Extreme Ultraviolet Camera) payload from 11:08 to 16:18 UT on February 24, 2025. The raw data were segmented into six consecutive intervals of 50 minutes each, resulting in six CSV files. The file names correspond to the following time windows: 11:18-12:08, 12:08-12:58, 12:58-13:48, 13:48-14:38, 14:38-15:28, and 15:28-16:18 UT. All observational values in the data files have been log10-transformed (base-10 logarithm). Users can open and read the CSV files using standard spreadsheet or data analysis software (e.g., Microsoft Excel, WPS, or Python Pandas). This dataset contains no missing data, and the internal structure of each file is consistent, allowing direct use for subsequent statistical analysis or visualization.In addition, this dataset contains the three-dimensional resistive MHD simulation of Earth's magnetosphere presented in the paper. The simulation code is provided as a pre-compiled, source-free executable for Linux x86-64 with its Intel MPI runtime bundled; the Fortran source code is not distributed. Two input files (the solar-wind/IMF driver input20250224 and the initial-state restart file steady_euvdtd) and the corresponding model output (disturb_euvrd) are included. Running the model requires 125 MPI ranks and about 2 GB of RAM per rank, and the output is stored as a raw little-endian real*4 stream on a 350×350×350 grid. IDL routines for reading and analysing the output are available at https://zenodo.org/records/22938699, and further details are given in the README file.
