Global climate model projections for the CMIP5 RCP8.5 emissions scenario produced as part of the UK Climate Projection 2018 (UKCP18) project. Data has been produced by the UK Met Office Hadley Centre, and provides information on changes in 21st century climate for the UK, helping to inform adaptation to a changing climate.

The set of 28 projections is a combination of 15 coupled model simulations produced by the Met Office Hadley Centre, and 13 coupled simulations from CMIP5 contributed by different climate modelling centres.

This data set provides information on changes in climate across the entire globe from 1900 to 2100 for RCP8.5. Each projection provides an example of climate variability in a changing climate, which is consistent across many climate variables at different times and spatial locations.

This dataset contains 60km for the UK only on the Ordnance Survey's British National Grid.

Process overview

This dataset was generated by the computation detailed below.
Title UKCP18 Climate Realisations for UK on OSGB grid from Global Runs
Abstract Climate model simulations made using the HadGEM3 model. The uncertainties in the projections of future climate are represented by the spread of the perturbed multi-model ensemble.
