Indian Scientists Develop Model to Predict Equatorial Electrojet

Context

Scientists at the Indian Institute of Geomagnetism (IIG) in Navi Mumbai have developed a groundbreaking model called the Indian Equatorial Electrojet (IEEJ) Model. This innovative tool is designed to enhance the accuracy of predictions for the Equatorial Electrojet specifically over the Indian sector. Utilizing data from ground-based magnetometers located at the Tirunelveli station near the southern tip of India, the model facilitates regular measurements of the Equatorial Electrojet.

Overview of Equatorial Ionospheric Processes

• Definition: The Equatorial Electrojet is a narrow band of intense electric current flowing eastward in the ionosphere at the geomagnetic equator, typically found at altitudes between 105 and 110 kilometers.
• Geographical Relevance: The phenomenon is especially relevant for India as the southern tip of the country is proximal to the Earth’s geomagnetic equator, where this strong current is present.

IEEJ Model Capabilities

• Simulation Tool: The IEEJ model features a web interface that facilitates simulations of the Equatorial Electrojet under varying conditions, such as different dates and levels of solar activity.
• User Interface: This accessibility allows researchers and practitioners to model and predict EEJ behavior, which is crucial for planning and operational purposes in related fields.

Practical Applications
The understanding and modeling of equatorial ionospheric processes are critical for several practical applications across various industries:

• Satellite Orbital Dynamics
• Global Navigation Satellite Systems (GNSS)
• Satellite Communication Links
• Electrical Power Grids
• Transmission Lines
• Oil and Gas Industry Pipelines
