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 ...
Météo-France has been running their Action de Recherche Petite Échelle Grande Échelle (ALADIN) mesoscale model for France, based upon the ECMWF global model, since 1995. [46] In July 1996, the Bureau of Meteorology implemented the Limited Area Prediction System (LAPS). [47]
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 ...
The Copernicus Climate Change Service [1] (abbreviated as C3S) is one of the six thematic services provided by the European Union's Copernicus Programme.The Copernicus Programme is managed by the European Commission and the C3S is implemented by the European Centre for Medium-Range Weather Forecasts (ECMWF).
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 Iran Meteorological Organization, also called the Met Department, is an agency of the Ministry of Roads and Urban Development of the Government of Iran. Headquartered in Tehran , it is the principal agency responsible for meteorological observations, weather forecasting and seismology , operating hundreds of observation stations across Iran .
