We pull directly from DWD (ICON-EU) and ECMWF open data—the same models used by professional meteorologists. No third-party APIs with aggressive rate limits.
- ICON-EU at 7km resolution for European routes
- ECMWF for extended 15-day forecasts
- 10 pressure levels from surface to FL390
- Updates every 3 hours from source

Safety-critical data handling
We never show "no warnings" when data is unavailable. If we can't fetch it, you'll know. Stale data is flagged. Because absence of data isn't the same as all-clear.
