  • 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.

  • Study of intercontinental transport of air pollutants by means of coordinated flights over the East coast of North America, the Azores and the West coast of Europe. ITOP was a component of the International Consortium for Atmospheric Research on Transport and Transformation (ICARTT), an international initiative which coordinated the efforts of various American and European groups who developed plans for field campaigns in the summer of 2004, with the aim of improving our understanding of the factors determining air quality over the two continents and over remote regions of the North Atlantic. This dataset includes ECMWF boundary layer, convective precipitation and cloud level forecast model output.

  • 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.

  • This data is provided to comply with the AGU''s data policy for the publication of Glauert et al., "Evaluation of SaRIF high-energy electron reconstructions and forecasts" in Space Weather, 2021. Each data file corresponds to a figure or table in the paper and covers the period from 1 March 2019 to 1 September 2019. The data sets are as follows: Figure 1 - SaRIF reconstructions of the >800 keV and the >2 MeV flux (in cm-2 s-1 sr-1) measured by the GOES 14 spacecraft. Figure 3 - SaRIF 24-hour forecasts of the >800 keV and the >2 MeV flux (in cm-2 s-1 sr-1) at the location of the GOES 14 spacecraft. Figure 5 - SaRIF reconstructions of the >800 keV and the >2 MeV flux (in cm-2 s-1 sr-1) measured by the GOES 14 spacecraft, with the improvements to the modelling detailed in the paper. Figure 6 - Simulated SaRIF 24-hour forecasts of the >800 keV and the >2 MeV flux (in cm-2 s-1 sr-1) at the location of the GOES 14 spacecraft, with the improvements to the modelling detailed in the paper. Table 6 - Simulated SaRIF 24-hour reconstructions and forecasts of the >800 keV and the >2 MeV flux (in cm-2 s-1 sr-1) at the location of the GOES 14 spacecraft when the outer boundary for the simulation is placed at L* = 6.6. These are the values used to produce the metrics in Table 6. This research was supported by the Natural Environment Research Council (NERC) Highlight Topic Grant NE/P01738X/1 (Rad-Sat), National and Public Good activity grant NE/R016445/1 and ESA contract 4000118861/16/D/MRP (SSA P2-SWE-XIII proto- type)

  • 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.

  • In support of the COAPEC Thematic Programme the BADC has extracted seasonal forecast ensemble data from the ECMWF MARS (Meteorological Archive and Retrieval System) archive. These data are also known as "Hindcasts" as they are forecasts run retrospectively. Since the data is part of the ECMWF Operational system BADC users must successfully apply for access to this dataset before they can obtain the data. The ECMWF produced two sets of runs, System 1 and System 2. The data archived at the BADC are the System 2 runs which use the atmospheric component Cy23r4 of the IFS (Integrated Forecasting System) with a horizontal resolution of TL95 at 40 levels in the vertical. This is the same cycle of the IFS used for the ERA-40 re-analysis. A detailed description of the ECMWF Seasonal Forecasting system can be found on the ECMWF web site. Products: The BADC has extracted monthly means, maxima, minima and standard deviations for the available surface variables from 1987 to 6 months before the present date. Atmospheric variables are only currently available as monthly means. The data is held as part of the main BADC Operational ECMWF archive. For each month there are six forecast months archived, with 5 ensemble members for 10 months of the year, and 40 ensemble members in May and November of each year from 1987-2001. From 2002 onwards there are 40 ensemble members per month. There are 33 parameters held on surface or single levels and 6 parameters available on pressure levels. The data is held on a regular 1.875 x 1.875 degree grid in GRIB format.

  • 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.

  • Regularly gridded operational data at 1.125 degree resolution from 2000 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.
