Predicting Solar Proton Events of Solar Cycles 22-24 using GOES Proton & Soft X-Ray Flux Statistics 后印本

摘要: Solar Energetic Particle (SEP) events and their major subclass, Solar Proton Events (SPEs), can result in unfavorable consequences to numerous aspects of life and technology, making them one of the most prevalent and harmful effects of solar activity. Garnering knowledge leading up to such events by studying proton and soft X-ray (SXR) flux data to alleviate the burdens they cause is therefore critical for their forecasting. Our previous SEP prediction study, Sadykov et al. 2021 indicated that it may be sufficient to utilize only proton and SXR parameters for SPE forecasts considering a limited data set from Solar Cycle (SC) 24. In this work we report the completion of a catalog of $\geq$ 10 MeV $\geq$10 particle flux unit (pfu) SPEs observed by Geostationary Operational Environmental Satellite (GOES) detectors operated by the National Oceanic and Atmospheric Administration (NOAA), with records of their properties spanning through SCs 22-24. We report an additional catalog of daily proton and SXR flux statistics. We use these catalogs to test the application of machine learning (ML) for the prediction of SPEs using a Support Vector Machine (SVM) algorithm. We explore how previous SCs can train and test on each other using both earlier and longer data sets during the training phase, evaluating how transferable an algorithm is across different time periods. Validation against the effects of cross-cycle transferability is an understudied area in SEP research, but should be considered for verifying the cross-cycle robustness of an ML-driven forecast.
