    • Nowcasting and Predicting the Kp Index Using Historical Values and Real-Time Observations 

      Shprits, Yuri Y.ORCIDiD; Vasile, Ruggero; Zhelavskaya, Irina S.ORCIDiD (Space Weather, 2019)
      Current algorithms for the real-time prediction of the Kp index use a combination of models empirically driven by solar wind measurements at the L1 Lagrange point and historical values of the index. In this study, we explore ...
