ECMWF aims to provide accurate medium-range global weather forecasts out to 15 days and seasonal forecasts out to 12 months. [11] Its products are provided to the national weather services of its member states and co-operating states as a complement to their national short-range and climatological activities, and those national states use ECMWF's products for their own national duties, in ...
It comprises a spectral atmospheric model with a terrain-following vertical coordinate system coupled to a 4D-Var data assimilation system.In 1997 the IFS became the first operational forecasting system to use 4D-Var. [2] Both ECMWF and Météo-France use the IFS to make operational weather forecasts, but using a different configuration and resolution (the Météo-France configuration is ...
The ECMWF reanalysis project is a meteorological reanalysis project carried out by the European Centre for Medium-Range Weather Forecasts (ECMWF). The first reanalysis product, ERA-15 , generated reanalyses for approximately 15 years, from December 1978 to February 1994.

The Copernicus Atmosphere Monitoring Service (CAMS) is a service implemented by the European Centre for Medium-Range Weather Forecasts (ECMWF), launched in November 11, 2014, that provides continuous data and information on atmospheric composition.
Metview makes use of other software packages developed at ECMWF. Metview is an extended MARS client, [ 9 ] and uses ecCodes [ 10 ] for GRIB and BUFR handling and Magics [ 11 ] for contouring and visualisation.
The ECMWF model, the Ensemble Prediction System (EPS), [8] uses a combination of singular vectors and an ensemble of data assimilations (EDA) to simulate the initial probability density. [9] The singular vector perturbations are more active in the extra-tropics, while the EDA perturbations are more active in the tropics.
Along with the NWS's Global Forecast System (GFS), which runs out to 16 days, the ECMWF's Integrated Forecast System (IFS), which runs out 10 days, the Naval Research Laboratory Navy Global Environmental Model (NAVGEM), which runs out eight days, the UK Met Office's Unified Model, which runs out to seven days, and Deutscher Wetterdienst's ICON ...
