TropoForecast

Local and regional tropo forecast for FMDX web server

Version 1.0

• Uses vertical refractive profiles (N according to ITU logic via temperature, humidity, and pressure)
• Considers pressure levels (1000–850 hPa) with elevation gradients
• Searches for strongly superrefractive gradients (threshold ~ −60 N/km instead of just "something below −39 N/km")
• Additionally considers wind shear in the layer with the strongest gradient, including conversion of direction/speed to u/v components
• Cleanly scales the result to a 0–10 index (based on Hepburn)

Important note

This plugin provides a very reliable trend and probabilities for Tropo DX. However, due to purely technical reasons (resolution of global weather models), a 100% guarantee of forecast reliability cannot be given. It is still recommended to consult forecasts such as Hepburn.
