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/
