2025-03-24 Coronal large-scale feature dataset for 3-day prediction of Kp index doi:10.57760/sciencedb.space.02534 en Time: 2010-2023 Spatial resolution: 5x5 This dataset contains the coronal magnetic field structure at 2.5 solar radii extrapolated based on the PFSS model, the Pch factor calculated from SDO/AIA 193Å solar images, and the historical values of the Kp index. These data can be used to predict the Kp index for the next three days.(X_all_raw. csv) Column name: PFSS-- {var_name}--{historical_time}d-- {grid_number}  1. var_name: thetaB, fs  2. historical_time: 0-4 days  3. grid_number: 0 1, 2, three 2. kp--rec-- {historical_time}d_24h_max  1. historical_time: 24-28 days 3.
