ECMWF Reanalysis v5
ERA5 is the fifth generation ECMWF atmospheric reanalysis of the global climate covering the period from January 1940 to present. ERA5 is produced by the Copernicus Climate Change Service (C3S) at ECMWF.
ERA5 provides hourly estimates of a large number of atmospheric, land and oceanic climate variables. The data cover the Earth on a 31km grid and resolve the atmosphere using 137 levels from the surface up to a height of 80km. ERA5 includes information about uncertainties for all variables at reduced spatial and temporal resolutions.
ECMWF Reanalysis of the 20th Century - Land
ERA-20CL is ECMWF's land surface reanalysis of the 20th century, from 1900-2010. It assimilates observations of land surface observations only.
ECMWF Reanalysis of the 20th Century - model integrations
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.
ECMWF Reanalysis of the 20th Century
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 vorticity levels.
ECMWF Reanalysis - Interim/Land
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 based on GPCP v2.1.
ECMWF Reanalysis v5 - Land
ERA5-Land is a reanalysis dataset providing a hourly high resolution information of surface variables over several decades at ~9km grid spacing and covering the period from 1950 to 5 days before the present.
ERA5-Land, developed by C3S at ECMWF, has been produced by replaying the land component of the ECMWF ERA5 climate reanalysis. Monthly aggregates of the hourly fields are available.
Coupled reanalysis of the satellite era
CERA-SAT is a reanalysis dataset spanning 8 years between 2008 and 2016. It has been produced within the scope of the ERA-CLIM2 project as a proof-of-concept for a coupled reanalysis with the full observing system available in the modern satellite age. CERA-SAT has been created using the CERA assimilation system and comprises an ensemble of 10 individual members.
