IFS Oper (ECMWF IFS HRES) is ECMWF’s global numerical weather prediction system for the medium range. It couples atmosphere, ocean, land surface, and sea ice in a single model. The analysis uses 4D-Var with an Ensemble of Data Assimilations to provide flow-dependent background errors. It ingests satellite radiances, GNSS radio occultation, scatterometer and altimeter winds, aircraft reports, radiosondes, and surface, buoy, and ship observations. Forecast fields include temperature, wind, humidity, precipitation, cloud, radiation, pressure, and a broad set of surface and pressure-level variables. Closely related suites include the ensemble system IFS ENS and the wave model IFS Wave.
