Synthetic‐Data‐Driven Supervised Learning for Pixel‐Wise Recognition of Ionogram Layer Traces

Journal of Geophysical Research: Machine Learning and Computation
The significance of automatic ionogram data interpretation is growing with the increasing number of ionosondes operating at minute‐level cadence. In recent years, deep‐learning models have substantially advanced ionogram pattern recognition.

Analysis of daytime medium-scale traveling ionospheric disturbances by two-dimensional maps of total electron content perturbation and ionograms

Учёные записки Казанского университета: Серия Физико-математические науки, 2017
To analyze midlatitude medium-scale traveling ionospheric disturbances (MSTIDs), the sufficiently dense network of GNSS receivers (more than 150 ground-based stations) have been used. For the first time, daytime MSTIDs in the form of their main signature
