**Goal**
|
| 99 |
+
The goal of this dataset is to provide high-fidelity training data for neural networks to predict ionospheric conditions—specifically electron density and signal interference—without requiring the extreme computational power of traditional physics engines.
|
| 100 |
|
| 101 |
+
Target Phenomenon: It models the "Ionic Ocean," referring to the fluid-like behavior of ionized particles in the Earth's upper atmosphere (ionosphere).
|
| 102 |
+
Problem Solved: Traditional models like SAMI3 (Self-consistent Analysis of the Model of the Ionosphere) are computationally expensive and slow. This dataset allows for the training of "surrogate models" that can predict results in real-time.
|
| 103 |
+
Application: Used for improving the accuracy of GNSS/GPS positioning by predicting and correcting for atmospheric delays and signal scintillation (flickering).
