Convection permitting climate model projections produced as part of the UK Climate Projection 2018 (UKCP18) project. The data produced by the Met Office Hadley Centre provides information on changes in climate for the UK until 2080, downscaled to a high resolution (2.2km), helping to inform adaptation to a changing climate.

The projections cover the UK and three time-slices (1981-2000, 2021-2040 and 2061-2080), for a high emissions scenario, RCP8.5. Each projection provides an example of climate variability in a changing climate, which is consistent across climate variables at different times and spatial locations.

This dataset contains 2.2km data on a 5km grid.

Note that these data were updated during summer 2021, after the correction of a coding error relating to graupel. Full details can be found on the Met Office website, on the Project News page: The previous version of the data will be retained on CEDA for twelve months until 21st July 2022.

UKCP18 Climate Realisations for UK on OSGB grid from Europe Regional Climate Model Realisations


The climate model projections are all variants of the limited-area atmosphere-only version of the Met Office Hadley Centre Global Environmental model (HadGEM3). They provide downscaled projections for the UK or Europe, driven by an ensemble of 60km Hadley Centre global coupled models HadGEM3-GC3.05.

This dataset consists of 12 projections from the 12km HadREM3-RA11M model. The model spans the UK and is driven by perturbed variants of the Met Office Unified Model Global Atmosphere GA7 model (HadREM3-GA705) at 12km resolution. The HadREM3-GA705 models were driven by perturbed variants of the global climate model, HadGEM3-GC3.05. Perturbations applied to the 12km RCM are consistent with the driving global climate model.

The convection-permitting climate model data has been interpolated using a conservative regridding scheme to the Ordnance Survey's British National grid.
