New interpretable ML model t-STEP predicts ionospheric irregularities

Researchers have developed t-STEP, a novel interpretable machine learning model designed to predict Total Electron Content (TEC) with high temporal resolution. This model operates at a 30-second cadence, enabling the detection of small-scale ionospheric irregularities that are crucial for satellite-based technologies like GPS. The t-STEP model demonstrates significant accuracy improvements over existing methods, including the IRI-2020 model, and shows promise in capturing dynamic ionospheric events during geomagnetic storms.

IMPACT This model's high-resolution predictions could improve the reliability of satellite-based navigation and communication systems by better accounting for ionospheric disturbances.
