Why teams choose it
Google says WeatherNext 3 is about five times sharper than WeatherNext 2 (5 km surface
vs a 25 km / 6-hour grid).
Forecast data is exposed through Earth Engine
BigQuery, Cloud Storage, and Maps Platform Weather API rather than the Gemini text API.
Google still tells people to use national weather services for official warnings.
Tradeoffs to know
- Vendor CRPS and Brightband claims should be rechecked on your region and lead time.
When not to use this
- This is not a chat or coding model and is not interchangeable with TimesFM-3.
- Not a substitute for official meteorological warnings.
