1 Introduction The ionosphere is one of the most important space regions for human activity, which can significantly influence short-wave related high-technology systems. Total electron content (TEC) is an important parameter to describe ionospheric behavior, thus its prediction is vital for the short-wave communication. However, the ionosphere is prone to disturbances during geomagnetic storm events.

6 Conclusions In this study, using the data from Van Allen probe A from 2013 to January 2018, we establish a model to predict the global evolution of hiss wave amplitudes based on DNN technology. The realistic evolution of hiss distribution from the model may have potential ability to overcome the limitation of in-situ satellite observation. In order to select the optimal parameters and corresponding historical time series, two methods of feature selection (LightGBM and PI) are used.
