  • 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.

  • This dataset contains T159 spherical harmonics gridded, model level, forecast timestep data 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.

  • N80 Gaussian gridded surface operational data from 1 March 1994 to present containing the ongoing analyses and forecasts produced by the most recent ECMWF Integrated Forecasting System (IFS) model. The IFS is regularly updated as improvements are made to the model, computing facilities and observations used in data assimilation.

  • T106 Spectral data from ECMWF's operational forecasting system from 1st March 1994 to 1st November 2000 containing analyses and forecasts produced by the ECMWF Integrated Forecasting System (IFS) model on model levels. Coverage is not complete for these data. Users needing data at this resolution as opposed to the T159 data should contact user support to discuss requirements.

  • Daily and monthly regularly gridded operational data at 2.5 degree resolution from 1 March 1994 to present containing the ongoing analyses and forecasts produced by the most recent ECMWF Integrated Forecasting System (IFS) model. The IFS is regularly updated as improvements are made to the model, computing facilities and observations used in data assimilation.

  • This dataset contains N80 Gaussian gridded, surface level, forecast timestep parameters from the European Centre for Medium-Range Weather Forecasts (ECMWF) Re-Analysis (ERA) 40 program from September 1958 to August 2002. 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 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.

  • 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.
