15-member coupled IFS (cycle 43R1) extended-range reforecast experiment covering the period 1989-2015. The atmosphere is configured with 91 vertical levels and uses the Tco399 cubic octahedral reduced Gaussian grid. The IFS is coupled hourly to the 75 level ...
dataset
Uses a sophisticated data assimilation methodology which includes a model bias correction. The ocean model used is forced by atmospheric daily surface fluxes, relaxed to SST and bias corrected. Ocean Reanalysis System 4 ICDC ORAS4 Uses a sophisticated data ...
dataset
An eddy-permitting ocean reanalysis spanning the period 1979–2012. Includes increased horizontal and vertical resolution, an prognostic sea-ice component, new versions of the ocean and data assimilation system, revised surface fluxes, new version and ...
dataset
The ECMWF OCEAN5 system is a new global eddy-permitting ocean-sea ice ensemble reanalysis analysis system. This Technical Memorandum gives a full description of the OCEAN5 system, with the focus on its Behind-Real-Time (BRT) component, the reanalysis product ...
dataset
An ensemble of ten atmospheric model integrations for the years 1899 to 2009/2010. There are two versions of the ERA-20CM atmospheric model integrations. Each is comprised of a 10-member ensemble using: Radiative forcing from CMIP5 Sea-surface temperature ...
dataset
The world's largest collection of pressure observations, developed by extracting observations from established international archives of meteorological variables and by combining these with observations made available by others organisations. International ...
dataset
ERA-20C is ECMWF's first atmospheric reanalysis of the 20th century, from 1900-2010. It assimilates observations of surface pressure and surface marine winds only. It is available on 37 pressure levels, 16 potential temperature levels, and 2 potential ...
dataset
ERA-Interim/Land is a global reanalysis of land-surface parameters from 1979-2010 at 80 km spatial resolution. It was produced with a recent version of the HTESSEL land-surface model using atmospheric forcing from ERA-Interim, with precipitation adjustments ...
dataset
ERA-40 is an ECMWF re-analysis of the global atmosphere and surface conditions for 45-years, over the period from September 1957 through August 2002. An atlas of key atmospheric variables was produced for ERA-40 ECMWF Reanalysis - 40 years ECMWF ERA-40 ERA-40 ...
