EuroCORDEX-UK

The EuroCORDEX-UK project supplements the UK national climate projections (UKCP18) using information from the international CORDEX initiative. Results, reports and data are available from this page.

About the EuroCORDEX-UK project

The 2018 UK Climate Projections (UKCP18) provide information about the future climate of the UK at coarse (60km), medium (12km) and local (2.2km) spatial resolutions. The medium-resolution projections are proving beneficial in understanding future climate risks to the UK. However, they were driven by a relatively small subset of global climate models and so may not sample the full range of uncertainty that is consistent with current scientific knowledge.

This research project extends the UKCP18 suite of climate projections by augmenting them with information from a broader range of high-resolution climate simulations, obtained from the EuroCORDEX downscaling experiment. The additional projections provide a more comprehensive sampling of uncertainty in high-resolution UK climate projections. In turn, this offers the potential to develop better informed strategies for adapting to, and mitigating the effects of, future weather and climate.

As well as providing access to additional climate projections for the UK, the project aims to provide insights into the physical plausibility of the various simulations; to assess the value added by considering high-resolution information; to identify the dominant sources of uncertainty in future projections of a variety of weather indices; and to assess the extent to which the existing UKCP ensemble provides a decision-relevant characterisation of this uncertainty. To achieve these challenging objectives, the project takes a multidisciplinary approach combining expertise in climate modelling, modern statistics and uncertainty quantification, and software engineering.

The project runs from October 2019 until January 2023, and is funded under the UK Climate Resilience Programme.

Data and software resources

As well as augmenting the existing UKCP18 archive, the project has produced a wide range of downloadable summaries of various climate indices over the UK. The augmented archive and computed summaries are available from the links below, along with software resources.

Data and summaries

  • Augmented UKCP18 archive. This contains future climate projections and historical runs from a large number of global circulation models (GCMs) and regional climate models (RCMs), from the EuroCORDEX and CMIP5 ensembles. The outputs have all been cropped to the region used for the UKCP18 projections, and regridded to the UKCP18 grid. Details of this processing can be found in the help pages for the plot explorer (see below). The data are hosted by the Centre for Environmental Data Analysis (CEDA) Archive.
  • EuroCORDEX-UK plot explorer. This analysis and visualisation tool is designed to allow rapid exploration of the EuroCORDEX-UK projections. Users can select climate indices, seasons and time periods of interest and can compare the various model outputs, produce maps of projections and historical biases in these indices, and quantify the dominant sources of variation and uncertainty within the projections. The plots and underlying data are downloadable directly from the plot explorer.
