UKCP18 BIAS-CORRECTED FUTURE CLIMATE PROJECTIONS

The UKCP18 RCM PPE is a Regional Climate Model (RCM) Perturbed Physics Ensemble (PPE) of climate projections produced for the UK Climate Projections 2018 project (UKCP18) by the Met Office Hadley Centre. These provide data at 12km resolution for the UK from 1981 to 2080 under a high emissions scenarios (RCP8.5). The original UKCP18 data are available from the CEDA archive.

However the RCMs shows a range of biases in their simulation of the UK's present-day climate and CRU PhD students have therefore applied two bias-correction methods to adjust the data to account for and remove many of these biases.

These bias-corrected UKCP18 RCM data at 12km resolution are available for other projects to use, provided due acknowledgement is given by citing the papers listed below.
