A Bidirectional Deep-Learning Algorithm to Forecast Regional Ionospheric TEC Maps

Abstract: The rapid evolutions in Artificial Intelligence (AI) and the Machine Learning era have significantly improved accuracy for ionospheric space weather forecasting models. The ionospheric Total Electron Content (TEC) forecasting is necessary to alert Global Navigation Satellite System (GNSS) users about ionospheric space weather influences on satellitereceiver radio communications. Precise modeling and forecasting of the ionospheric TEC are critical for reliable and accurate GNSS applications. In this paper, a de… Show more

“…In recent years, various deep learning methods have been utilized for TEC prediction (Li et al., 2022; Liu et al., 2022; Mallika et al., 2018; Ren et al., 2022; Ruwali et al., 2020; Sivakrishna et al., 2022; Tang, Li, Ding, et al., 2022; Tang, Li, Yang, & Ding, 2022; Ulukavak, 2021; Xiong et al., 2021). These studies demonstrate that deep learning methods are well‐suited for handling complex and non‐linear features in the ionosphere.…”

“…Therefore, the regional model has been the mainstream of research in recent years, and the proposal of the regional model is also the inevitable demand of future communication system applications (Wang, Yang, & Yan, 2021). In decades, researchers have gradually proposed specialized TEC regional prediction models in China (Xiong et al., 2021), Japan (Mallika et al., 2019), India (Sivakrishna et al., 2022), Korean Peninsula (Jeong et al., 2022), South Africa (Ssessanga et al., 2019), Antarctic region (Yao et al., 2021), low latitude region (Zewdie et al., 2021), and ocean (Ren et al., 2022). On the other hand, from the perspective of the methods used for modeling, the spatial reconstruction of TEC can be divided into mathematical and machine learning‐based methods.…”

“…6 Even when input sequences are indestructible or stochastic in nature, this algorithm can bridge time breaks in more steps without sacrificing brief time break capabilities. 7,8 The long-term dependencies of RNN, using current data, can make ARTICLE pubs.aip.org/aip/adv precise predictions; however, it cannot predict data stored in longterm memory. These dependencies are resolved using the LSTM technique, which makes the input of a current step the outcome of the previous step.…”
