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 the time period 01/12/1980 to 30/11/2080 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 regionally averaged to 23 UK River Basins. Further information on this dataset and UKCP18 can be found in the documentation section.

Note that the first version of this data covered three time slices (1981-2000, 2021-2040 and 2061-2080), and in March 2023 the remaining time slices (2001-2020, 2041-2060) were added. In December 2024, an additional four downscaled CMIP5 members were added . Also note that the data for the three time slices (1981-2000, 2021-2040 and 2061-2080) 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 UKCP Project News page in the documentation section.
