The Short-Term Prediction of Length of Day Using 1D Convolutional Neural Networks (1D CNN)

Abstract: Accurate Earth orientation parameter (EOP) predictions are needed for many applications, e.g., for the tracking and navigation of interplanetary spacecraft missions. One of the most difficult parameters to forecast is the length of day (LOD), which represents the variation in the Earth’s rotation rate since it is primarily affected by the torques associated with changes in atmospheric circulation. In this study, a new-generation time-series prediction algorithm is developed. The one-dimensional convolutional n… Show more

“…When training a model on reflectivity curves with fixed discretization, a 1D CNN embedding network is parameterefficient and makes better use of the sequential characteristics of the data. While less popular than their 2D counterparts, 1D CNNs have been successfully used in a variety of tasks involving 1D signals, such as automatic speech recognition (Collobert et al, 2016) and time-series prediction (Guessoum et al, 2022). The 1D CNN, as shown in Fig.…”
