Monitoring and Forecast of Ionospheric Disturbances
Welcome to the Transionospheric Radio Link - Monitoring and Forecast of Ionospheric Disturbances service
Overview
The service "Transionospheric Radio Link - Monitoring and Forecast of Ionospheric Disturbances" aims to provide an estimate of the occurrence risk of ionospheric disturbances, including monitoring and detection of ionospheric phenomena causing local disturbances of electron density and detection of geomagnetic storms. This service is currently under development. The aim is to consider the following ionospheric phenomena:
- trough,
- Travelling Ionospheric Disturbances (TIDs),
- patches,
- depletions and
- D-region absorption.
Currently, this service provides vertical TEC maps, URSI ionospheric parameters and ionospheric perturbation products like the equivalent slab thickness and Rate Of Change of TEC Index (ROTI).

User Manual
While quiet ionospheric conditions are considered in many applications, disturbed conditions limit the functionality and availability of most systems. Prominent ionospheric perturbations are e.g.
- The ionospheric trough: an electron density depletion near the auroral region.
- Ionospheric patches: very localised regions with strong electron density deviations. Patches occur predominantly in the polar regions.
- Travelling Ionospheric Disturbances (TID): TIDs are signatures of atmospheric gravity waves. The atmospheric waves cause perturbations in the winds and density of the thermosphere, which is impacting the electron density.
- Depletions: Electron density depletions in mid-latitudes often occur during high geomagnetic activity. They are related to mid-latitude spread-F plumes (or plasma bubbles).
- D-region absorption: the D-region describes the lower ionosphere at about 80 km altitude. Enhancement of the D-region electron density can cause absorption of high frequency (HF) radio waves used for long-range communication. These D-region electron density enhancements can be primarily attributed to solar flares (X-ray) and radiation storms.
