MEEMD-ARMA Residual Modified Ionospheric TEC Prediction Model
Abstract To determine the characteristics of total electric contents data and the deficiencies of the original models, a model combining modified ensemble empirical model decomposition and ARMA residual correction model is proposed. We use the total electric contents data provided by IGS in 2015, and use the three models to predict the data within 5 days. The results indicate that the mean relative precision of TEC predicted is 96% by the improved model , while the EMD-ARMA model and ARMA model are 94.5%, 93% accurate, respectively.
