Global analyses from the European Centre for Medium-Range Weather Forecasts (ECMWF) from 1994 - present. This dataset collection follows on from the ECMWF Re-Analysis (ERA-15 and ERA-40) datasets with the same parameters at identical resolutions. Data is available in a number of resolutions and vertical level types. Some Monthly means and Seasonal Forecast data (1987-present) are also available.

The mesoscale forecast data are of tephigrams which show the temperature at given pressures in the atmosphere. The dataset also contains maps of wind convergence and total rainfall over the UK and northern Europe. The data were collected from observation stations in the UK, Belgium, and France on the 7th of July 2004. Temperature and dew point data from radiosondes are plotted on these diagrams to allow calculations of convective stability or convective available potential energy (CAPE) Wind barbs are plotted to indicate the winds at heights of 10 metres and at 900 hectopascals. Plots are also available of total rainfall.

Orography files for the European Centre for Medium-Range Weather Forecasts's (ECMWF) operational forecast model. Archived data are on the 1.125 and 2.5 degree regular longitude-latitude grids, N80 (full) Gaussian grid and Spectral (T106) grid. These files are updated each time the model orography is changed. For the Operational data (March 1994-present day) there are orography files for the following dates: 1 March 1994, 4 April 1995, 8 September 1996, 10 December 1996, 1 April 1998 and 12 October 1999. The orography for the ERA-15 project was constant so only the start date orography is stored here: i.e. for 1 Jan 1979. The spectral orography file only contains the orography data (surface geopotential). Depending on the age and grid type, the remaining files contain some of the constant fields: Geopotential (at the surface, orography), Standard deviation of orography, Anisotropy of subgrid scale orography, Angle of subgrid scale orography, Slope of subgrid scale orography, Land/Sea mask, EW component of sub-grid scale orographic variance, NScomponent of sub-grid scale orographic variance, NWSE component of sub-grid scale orographic variance, NESW component of sub-grid scale orographic variance.

This dataset contains 6-hourly monthly average, N80 Gaussian gridded, surface level, forecast timestep parameters from the European Centre for Medium-Range Weather Forecasts (ECMWF) Re-Analysis (ERA) 40 program from January 1958 to December 2001. ERA-40 followed on from the ERA-15 re-analysis project. Access limited to UK based academic researchers only. These data are GRIB formatted.

This dataset contains daily monthly average, N80 Gaussian gridded, surface level, forecast timestep parameters from the European Centre for Medium-Range Weather Forecasts (ECMWF) Re-Analysis (ERA) 40 program from January 1958 to December 2001. ERA-40 followed on from the ERA-15 re-analysis project. Access limited to UK based academic researchers only. These data are GRIB formatted.

Operational data from 1st January 2002 to present containing the ongoing analyses and forecasts produced by the most recent ECMWF Integrated Forecasting System (IFS) model. Data are available at the resolutions used for the ERA 40 reanalysis project - i.e. reduced Gaussian N80 for surface data and spectral T159 for upper air data. The IFS is regularly updated as improvements are made to the model, computing facilities and observations used in data assimilation.

Surface level forecast parameters on a reduced N256 Gaussian grid from the European Centre for Medium-Range Weather Forecasts (ECWMF) ERA-Interim programme. The ERA-Interim global atmospheric reanalysis of the covers 1979 to August 2019. This follows on from the ERA-15 and ERA-40 re-analysis projects This subset of the ERA-Interim dataset contains 45 parameters.
