23 Aug 2017 – Peak virtual height maps of the F2-layer (h’F2) have been removed from the website (they were at the bottom of http://www.sws.bom.gov.au/HF_Systems/1/4). Virtual height is determined from the time required for the radiowave to travel to the ionospheric layer, assuming that the wave is propagating at the speed of light. For instance, an ionogram shows a series of transmitted radiowave frequencies and the virtual height at the reflection point, if any, of these frequencies. Using modelling techniques, the frequency vs virtual height profile of the ionosphere can be converted to a frequency vs true height profile. It has therefore been decided that the virtual heights (h’F2) maps will be replaced by the true height maps of the F2-layer (hmF2) on the website. An update will be provided once this has been accomplished. More
