The source simulations were originally run at 2.2km resolution. The dataset includes all 16 ensemble members. The data cover Great Britain at 1km resolution on the British National Grid and are limited to grid cells where the model and relevant observational reference data overlap. Temporal coverage is December 1980 to November 2080 at hourly resolution. The cumulative distribution function transform (CDFt) method was trained over December 1990 to November 2010 using CEH-GEAR1hr v2 for precipitation and HadUK-Grid version 1.3.1 for temperature. Data are supplied as monthly NetCDF-4 files. The dataset is intended for hydroclimatic impact assessments and related climate-risk studies.

The 5 km fields were remapped to the 1 km grids of the reference datasets: CEH-GEAR1hr (hourly precipitation; Newcastle University and UKCEH) and HadUK-Grid v1.3.1 (air temperature; Met Office; hourly values derived from daily maximum and minimum temperature). Four bias correction methods (quantile mapping, ISIMIP3BASD, scaled distribution mapping, CDFt) were screened using ensemble member 01 over two 10 x 10 grid-cell blocks in the Scottish Highlands and East Anglia. CDFt performed most consistently and was applied to hourly precipitation and temperature for all 16 members over the full domain, trained over December 1990 to November 2010. Processing used the ibicus Python package on the JASMIN facility. Full details are given in Zha, He and Lowe (Journal of Hydrology, submitted).
