One‐Day Forecasting of Global TEC Using a Novel Deep Learning Model

Abstract: The total electron content (TEC) is the total number of electrons along a path between a radio transmitter and a receiver. The unit of TEC (TECU) is defined as 10 16 electrons/m 2 , and 1 TECU corresponds to a 0.163 m range delay on L1 frequency. TEC is used as one of the major parameters in space weather and an indicator of ionospheric disturbance. The accurate measurement of TEC provides us with useful information on satellite communications, navigation, national defense, and aviation. The International Glob… Show more

“…Wang et al (2020) directly used an adaptive autoregressive model to predict grid point vertical total electron content values, avoiding twice accumulated errors by predicting spherical harmonic coefficients. Lee et al (2020) used a conditional generative adversarial network to predict the global TEC maps one day in advance, the RMSE from the model is 1.74 TECU.…”

“…Several existing maps were used as references to interpolate missing values in some regions, such as the oceans. The TEC maps can also be predicted two hours in advance with an LSTM (Liu et al, 2020) or one day in advance with a GAN (Lee et al, 2021). Further, a DNN is used to estimate the relationship between electron temperature and electron density in small regions (Hu et al, 2020 Note.…”

“…The DL technique based on conditional generative adversarial networks (cGAN) is used to forecast global TEC maps one-day ahead [8]. Saed et al have proposed a solar flare predictions model using the ML technique, the Support Vector Machine (SVM) model with Center for Orbit Determination in Europe (CODE) Global Ionospheric TEC maps (GIM) TEC data.…”
