Scientists have developed <\/span>a model for high frequency (HF) radio wave propagation through the ionosphere which helps in studying the impacts of space weather effects on the ionosphere and Sky wave communication systems.<\/span><\/p>\n

What is Ionosphere?<\/b><\/h2>\n

The ionosphere is a region of Earth\u2019s upper atmosphere ranging from about 100 – 1000 km and acts as a gateway for radio communication between the ground and space.\u00a0<\/span><\/p>\n

Radio waves of certain frequencies (HF band) are reflected back to the ground by the ionosphere which facilitates long-distance HF communications beyond the horizon, known as Skywave communications.\u00a0<\/span><\/p>\n

Despite the increasing use of satellite communications, traditional long-distance high-frequency (HF) radio communication remains a vital means of communication during situations like natural disasters, mid-ocean surveillance, over-the-horizon target detection, and so on.\u00a0\u00a0<\/span><\/p>\n

Severe ionospheric disturbances that arise due to a range of space weather events like Solar flares, Coronal Mass Ejections (CMEs), and Geomagnetic storms significantly affect Skywave communications.\u00a0\u00a0<\/span><\/p>\n

This variability of the ionosphere due to disturbances in space weather can significantly limit the usage of Skywave communications.<\/span><\/p>\n

What have the scientists developed?<\/b><\/h2>\n

Scientists have developed a model for high frequency (HF) radio wave propagation through the ionosphere which helps in studying the impacts of space weather effects on the ionosphere and Sky wave communication systems.<\/span><\/p>\n

The HF radio propagation model developed by scientists has important applications in planning the right strategies for the operation of Sky wave communication systems during active space weather periods.<\/span><\/p>\n","protected":false},"excerpt":{"rendered":"
