The web sites of the European Centre for Medium-Range Weather Forecasts (ECMWF) present numerical weather predictions, news and the latest information on ECMWF activities to a broad spectrum of users interested in medium-range weather forecasting.
The web sites offer users the possibility to learn more about ECMWF's organisation, to research specific areas and programmatic themes, and to access ECMWF products and services. They also serve as channels to link visitors to ECMWF's more specialised scientific and technical sites, which are of interest to various weather and climate-related communities.
Access to ECMWF’s web sites is provided from ECMWF’s headquarters in Reading, UK.

Access to and use of protected content
Some content and page areas on the ECMWF web sites are protected by access control and require an ECMWF user-id in order to view. ECMWF user-ids are not available to members of the public. They are available to representatives of the national meteorological and hydrological services in ECMWF’s Member States and Cooperating States. They are also available to representatives of other organisations, which have agreed special licences for use of ECMWF’s products and services.
That content, which is only accessible via an ECMWF user-id, must be used in accordance with the relevant terms, previously agreed between ECMWF and the organisation, for which the user is a representative.
Limiting access to our web sites
The nature of some of the data and services provided via ECMWF's web sites means that in certain circumstances it is possible for individual users to affect the functionality, availability or response of the web site for other users. ECMWF will attempt to resolve such issues without adversely affecting use but in such cases where it is not possible to resolve the issues, ECMWF will have the option to regulate, limit or ban access to part of, or all of, our web sites, based on incoming IP address, user-id or any other access characteristic ECMWF feels is necessary to solve the problem. When ECMWF has taken such action, reasonable attempts will be made to communicate the issue to the user in order that full service may be restored.
Forums and discussions
The ECMWF web site may contain bulletin boards, chat rooms, access to mailing lists and other message and communication facilities (collectively termed 'forums'). Users agree to use forums solely to send and receive messages and materials that are strictly related to the particular forum.
When using an ECMWF forum, users agree not to do any of the following:
- Users may not download, distribute or otherwise publish through the ECMWF web site any content which is libellous, defamatory, obscene, pornographic, abusive or which, in any way, violates any laws;
- Forums are for non-commercial use only. Users may not distribute or otherwise publish any material containing any solicitation for funding, advertising or solicitation for goods or services without requesting and receiving prior written approval from ECMWF;
- Users shall not delete any author attributions, legal notices, proprietary designations or labels from any file that is downloaded nor falsify the origin or source of software or other material contained in a file that is downloaded.
ECMWF does not and cannot review every message posted by users on forums and is not responsible for the content of any messages posted. ECMWF reserves the right to delete, move or edit, at its sole discretion, messages that it deems abusive, defamatory, obscene, in violation of copyright laws or otherwise unacceptable. Users shall remain solely responsible for the content of their messages.
