Data Sources & Our Approach

ZeroTurb's Custom Algorithm: We've developed a proprietary ZeroTurb Index (ZTI) algorithm that combines three meteorological indices weighted by their predictive accuracy. This gives you transparent, passenger-focused turbulence probability instead of vague categories.

This forecast integrates data from:

ECMWF Open Data - Global atmospheric model (wind/temperature at 13 flight levels)
NOAA Aviation Weather Center - Pilot Reports (PIREPs), SIGMETs/AIRMETs, TAFs
NOAA Space Weather Prediction Center - Aurora forecasts for polar routes
AviationStack API - Flight schedules and airline operational data

Disclaimer: This forecast is for informational purposes only. Always consult official aviation weather sources and follow ATC guidance.

How accurate are turbulence alerts? Alerts are based on updated forecast models and pilot reports, and can change as departure approaches.
