I am pleased to announce the availability of the worlwide refractive index forecasts.
Maps is fully customizable and show refractive index from 80° S to 80° N worlwide.
A click on the map will show the average index for a specific QRA locator.
Furthermore it can display conditions for the 28 lasts days.
Have a try here: http://tropo.f5len.org/WW/
