DTN Enhanced Flight Hazards Forecast Intelligence

NOTE: If your are currently using GRIB2 0.5 degrees icing/turbulence layers, you will have to switch to the 0.25 degree GRIB2 files coming from the EFH stack.

DTN hosts a proprietary suite of Flight Hazards forecast data that can be used for improved flight planning or situational awareness.  The Enhanced Flight Hazards (EFH) dataset includes forecasts for:

• Eddy Dissipation Rate Turbulence

• Airfoil-specific Icing

• Global Thunderstorm Updraft

• Rapid Update Convective Turbulence Forecast

• High Ice Water Content

The Flight Hazards data is available via GRIB2 format and also via a contoured polygon shape and GeoJSON files.

In addition, DTN’s Flight Hazard information can be access via the WeatherSentry API.
