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 ...
The ECMWF model, the Ensemble Prediction System, [85] uses singular vectors to simulate the initial probability density, while the NCEP ensemble, the Global Ensemble Forecasting System, uses a technique known as vector breeding. [86] [87]
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 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 .
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.
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 ...
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 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.
