This data set contains net fluxes at the surface, atmospheric mixing ratios at model levels, for carbon dioxide (CO2), methane (CH4) and nitrous oxide (N20).

Climate forcing, also known as Radiative Forcing, determines the change in globally-averaged temperature change due to the natural or human-induced changes to the energy budget.

The climate forcing estimates of CAMS quantify the climate forcings exerted by changes in atmospheric carbon dioxide, methane, and ozone, and their uncertainties.

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.

The ERA-15 production system generated re-analyses for 15 years (1979-1993) using a special version of their 1995 operational data assimilation system and model. The resulting analyses include full model resolution analyses or reduced resolution analyses and climate and statistics data.

There is a picture gallery for ERA-15.

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

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 2-3 months 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.

ERA-Interim is a global atmospheric reanalysis from 1979, continuously updated in real time. The data products include a variety of surface parameters, describing weather as well as ocean-wave and land-surface conditions. It further includes parameters covering the troposphere and stratosphere, offering a range of 60 pressure levels.

It’s successor is the ERA5 reanalysis from the Copernicus Climate Change Service.

CERA-20C is the ECMWF 10-member ensemble of coupled climate reanalyses of the 20th century, from 1901-2010. It is based on the CERA assimilation system, which assimilates only surface pressure and marine wind observations as well as ocean temperature and salinity profiles. It is available on 37 pressure levels.

It is an outcome of the ERA-CLIM2 project.

There are two versions of the ERA-20CM atmospheric model integrations.

Each is comprised of a 10-member ensemble using:

The Monitoring Atmospheric Composition and Climate (MACC) Reanalysis is a global reanalysis data set of atmospheric composition (AC), made available by the Copernicus Atmosphere Monitoring Service (CAMS).  The dataset covers the period 2003 to 2012.

The spatial resolution of the data set is approximately 80 km (T255 spectral) on 60 vertical levels from the surface up to 0.1 hPa for the analysed species and 1.125° by 1.125° at the same 60 levels for the other chemical species.
