The area within the green bands is known as the auroral zone.
Radio signals passing through these auroral zones will experience increased signal degradation
in the form of fading, multipathing and absorption.

VHF / UHF Propagation
VHF Propagation Map:
This map shows actual radio propagation from stations operated near 144 MHz.
It uses data gathered by Automatic Packet Reporting System-Internet Service (APRS-IS) from packet stations in the amateur radio service.
Go to: VHF Propagation Map
Tropospheric Ducting Forecasts:
The areas noted in the forecast have the necessary atmospheric conditions to produce tropospheric bending of VHF, UHF and/or microwave radio waves. Tropospheric bending extends the range of radio & TV stations well beyond their normal limit and thus increases interference amongst stations as well.
