SMILE Synthetic Orbit Datasets with Soft Proton Flux Predictions (2025–2028)

Two whitespace-delimited datasets providing synthetic SMILE orbital ephemerides, space-weather parameters (Cycle-23 analog), FootType (T96/IRBEM), and XGBoost-based soft-proton predictions (92.2–159.7 keV) for SMILE's planned first 3 years of mission life from 2025-10-01 to 2028-09-30. We provide two scenarios: near-median solar-wind conditions and a disturbed subset (Vx below the 5th percentile). Rows with r<6 R_E are excluded. Columns, parsing instructions (datetime split into date/time tokens), coordinate system (GSE), and usage notes are detailed in the included metadata file. Timestamps and positions originate from the Innovation Academy for Microsatellites (IAMC), Chinese Academy of Sciences, China, provided in a J2000 Position–Velocity file (7 columns; time, X, Y, Z, Vx, Vy, Vz; original filename: SMILE_GSEAxesPosVel.txt). In this deposit, we retain timestamps and positions only (x_GSE, y_GSE, z_GSE; km) and omit velocities.
