A subset of ECMWF real-time forecast data from the IFS and AIFS models is made available to the public free of charge. Their use is governed by the Creative Commons CC-BY-4.0 licence and the ECMWF Terms of Use. This means that the data may be redistributed and used commercially, subject to appropriate attribution.
Accessing this data, or arranging for any open data to be delivered directly to you, may be subject to Service Charges and a Service Agreement. If you are interested, please see our Service Agreement and Use Cases page.

New from 20 October 2026
- A finer 0.1° resolution is now published alongside the existing 0.25°, for the IFS streams (the AIFS streams remain 0.25° only). It is produced from the same high-resolution (~9 km) forecast. See What's new at 0.1°.
- At 0.1°, each run is split into separate surface and pressure-level files (
-sfcand-pl), so users in low-bandwidth regions can take only what they need. The 0.25° data stays combined. - The 0.1° data is published about two hours after the 0.25° data, with its own WIS2 notifications. Plan for this if your workflow expects both at once.
- The GRIB packing precision is now tuned per parameter (bits-per-value), making files smaller without losing usable information. See Bits per value.
Bits-per-value reduction
Each value is stored in a fixed number of bits: more bits give finer steps and larger files. From 20 October 2026, precision is set per parameter based on what each field actually needs, rather than being inherited from the production and archive settings. The same packing applies to all open data — 0.25° and 0.1°, IFS and AIFS.
Fields that are read directly (for example, 2 m temperature) can use fewer bits, because the rounding is far below the accuracy of the forecast itself. Fields used to compute gradients (pressure, geopotential) keep more bits, because differencing amplifies small-scale rounding. Nothing that is used is lost. The full rationale is on the Bits per value page.
Product description
These products are a subset of the full Catalogue of ECMWF Real-time Products and are based on the medium-range (high-resolution and ensemble) and seasonal forecast models.
IFS data are published at two resolutions: the existing 0.25 degrees and, from 20 October 2026, a finer 0.1 degrees - both produced from the same IFS model and interpolated to a lat/long grid. The lower resolution data are released at the end of the real-time dissemination schedule, while the higher resolution IFS data are released 2h after the low resolution products. AIFS data are released as soon as the data are produced.
For further details about the available AIFS products, see the dataset descriptions for the Deterministic AIFS and Ensemble AIFS.
Products are provided in GRIB2 format unless stated otherwise.
Important:
-
System stability and access limits: To ensure the stability of our systems and to preserve resources for operational activities, access to the Open-Data Portal is currently limited to between 500 and 2000 simultaneous connections. This variable limit helps ensure reliable service for operational users, especially during periods of high demand.
-
Rolling archive and data availability: ECMWF Open Data provides access to real-time forecast data on a rolling archive basis. Data are retained for the most recent 12 forecast runs, corresponding to approximately 2–3 days of forecasts based on the four daily IFS and AIFS cycles (00, 06, 12 and 18 UTC). To access the full historical data archive, see the Service Agreements and Use cases for more information.
Alternative access methods and cloud platforms
For improved global accessibility and added redundancy, the ECMWF Open Data subset is replicated and available on major public cloud platforms, including Amazon Web Services (AWS), Microsoft Azure and Google Cloud Platform (GCP). These alternative access methods can be particularly useful for users with connectivity limitations, during high-demand periods, or when facing performance constraints when accessing the Open-Data Portal directly. Users can access the data directly via these public cloud storage services or use the ecmwf-opendata Python client, which lets you select the data source (ecmwf, aws, azure, or google) while providing a consistent interface across platforms. If you have difficulty accessing the Open-Data Portal directly, we recommend retrieving the data from one of these cloud service providers. For more detailed technical documentation, file naming conventions, and download examples, please see the ECMWF Open Data technical documentation.
