DMSP Cusp Crossing Database (1987–2014) and Trained XGBoost Model for Cusp Location Prediction

This dataset accompanies the paper: Zhu, Y. and Toffoletto, F. R. (2026). Predicting Ionospheric Cusp Location from Solar Wind: An XGBoost Model Trained on 27 Years of DMSP Data. Journal of Geophysical Research: Space Physics (in preparation). Contents: - cusp_crossings_1987_2014.csv: 48,056 DMSP cusp crossings (F06–F18, 1987–2014) with equatorward/poleward MLAT/MLT boundaries and matched OMNI solar wind/IMF features (74 features including 15/30/60-minute history statistics). Cusp identification follows Newell and Meng (1988) criteria. After removing records with missing solar wind data, 39,668 crossings remain for model training.
