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 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.

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.

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.

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.

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.

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.

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.

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.
