Description
WeatherNext Graph is an experimental dataset of global medium-range weather forecasts produced by an operational version of Google DeepMind's graphical neural network weather model.
The experimental dataset includes real-time and historic data. Real-time data is any data that relates to a time that is no more than 48 hours in the past ("Real-Time Experimental Data"), while historic data is any data that relates to a time that is more than 48 hours ago ("Historic Experimental Data"). This dataset includes major surface fields including temperature, wind, precipitation, humidity, geopotential, vertical velocity, and pressure. The spatial resolution is 0.25 degrees. Forecast init times have 6 hour resolution (00z, 06z, 12z, 18z). Forecast lead times have 6 hour resolution up to a max lead time of 10 days.
If you are interested in accessing the experimental dataset, please fill out this WeatherNext Data Request form.
More information on the model is in "Learning skillful medium-range global weather forecasting". The model used to produce this experimental dataset is an operational version derived from that research model (formerly known as GraphCast). Please note that the accuracy of this operational model may not directly correspond to the accuracy reported for the research model, and that additional variables may be included in this forecast dataset.
If you have any questions on using this experimental dataset, or would like to use it for purposes not currently permitted under the terms of use set out below, please contact weathernext@google.com.
Dissemination Schedule
All steps are released at once. All times are in the UTC time zone and are rough estimates (with typical ± 15 minutes variance). On occasion, times may vary up to ± 60 minutes or more. If data delivery exceeds +60 minutes, please inform us via weathernext@google.com.
| Forecast runs (init time) | Forecast dissemination schedule |
|---|---|
| 00:00 | 06:45 |
| 06:00 | 12:45 |
| 12:00 | 18:45 |
| 18:00 | 00:45 |
Accessing Raw Data (.zarr)
