Page Summary
-
The WeatherNext Graph dataset provides experimental global medium-range weather forecasts from an operational version of Google DeepMind's graphical neural network weather model.
-
This dataset contains both real-time data (within the last 48 hours) and historic data (older than 48 hours), covering major surface fields like temperature, wind, precipitation, and more.
-
The data has a spatial resolution of 0.25 degrees, with forecast initiation times every 6 hours and lead times up to 10 days, also with 6-hour resolution.
-
Access to this experimental dataset requires filling out the WeatherNext Data Request form, and raw historic data in .zarr format is also available upon request.
-
Different terms of use and citation requirements apply to the Real-Time and Historic Experimental Data, with third-party materials also potentially subject to separate conditions.
This dataset is part of a Publisher Catalog, and not managed by Google Earth Engine. Contact weathernext@google.com for bugs or view more datasets from the WeatherNext Catalog. Learn more about Publisher datasets.

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)
A bucket containing the raw .zarr files for the historical dataset
("Historic Experimental Data") is available at gs://weathernext/59572747_4_0/zarr. To gain access to
the bucket, please request access through the same WeatherNext Data Request form,
and note your interest in receiving access to the raw .zarr files.
