European Centre for Medium-Range Weather Forecasts

The European Centre for Medium-Range Weather Forecasts (ECMWF) is an international organisation based at Reading, England that was founded in 1975.


The objectives of the ECMWF are:
*Development of numerical methods for medium-range weather forecasting
*Preparation of medium-range weather forecasts for distribution to the member states
*Scientific and technical research directed to the improvement of these forecasts
*Collection and storage of appropriate meteorological data.

Work and Projects

The ECMWF has been producing operational medium-range weather forecasts since 1979-08-01.

It has run two "re-analysis" projects, the first ECMWF re-analysis (ERA-15) project generated reanalyses from December 1978 to February 1994.The ERA-40 project generated reanalyses from September 1957 to August 2002.

The history of ECMWF is recorded in the book: "Medium-Range Weather Prediction - the European Approach" by Austin Woods, published Springer 2005.


The ECMWF members are of 18 European countries: Austria, Belgium, Denmark, Finland, France, Germany, Greece, Republic of Ireland, Italy, Luxembourg, The Netherlands, Norway, Portugal, Spain, Sweden, Switzerland, Turkey, United Kingdom

The ECMWF has co-operation agreements with other states: Croatia, Czech Republic, Estonia, Iceland, Lithuania, Hungary, Morocco, Romania, Serbia, Slovenia.


ECMWF is based at Shinfield Park, Reading, England. It shared grounds with the UK Met. Office College until Summer 2002, before the college was relocated to Exeter ahead of the move of the Met. Office Headquarters from Bracknell in 2003. The land the Met Office College was on is now used by residential housing.
