Abstract

Gridded daily meteorological variables over the United Kingdom at 1 km resolution for the years 1980-2080. This dataset is an ensemble of four different realisations of future climate for each of four different representative concentration pathway scenarios (RCP2.6, RCP4.5, RCP6.0 and RCP8.5), provided both with and without bias correction. This dataset contains time series of daily mean values of air temperature (K), specific humidity (kg kg-1), relative humidity (%), wind speed (m s-1), downward longwave radiation (W m-2), downward shortwave radiation (W m-2), precipitation (kg m-2 s-2) and surface air pressure (Pa). It also contains time series of daily minimum air temperature (K), daily maximum air temperature (K) and daily temperature range (K). The data are provided in gridded netCDF files at 1 km resolution aligned to the Ordnance Survey / British National Grid. There is one file for each variable for each month of the daily data. Also provided are monthly, seasonal and annual means, for which there is one file for each variable for each time resolution. Additionally twenty year mean-monthly (Jan-Dec) climatologies at ten year intervals are provided, for which there is one file for each variable for each twenty year time slice. The projections use a 360-day calendar, where each month consists of 30 days.

Data lineage:

This dataset was derived from four ensemble members of the United Kingdom Climate Projections 2018 (UKCP18) Regional Projections on a 12km grid over
the United Kingdom for 1980-2080 (https://catalogue.ceda.ac.uk/uuid/589211abeb844070a95d061c8cc7f604, v20190731), which is a twelve member perturbed parameter ensemble of climate model projections for representative concentration pathway (RCP) scenario RCP8.5. Selected daily UKCP18 RCM variables were downscaled to 1 km using adapted Climate, Hydrology and Ecology research Support System (CHESS) downscaling methodology, taking into account topographic information. Ancillary datasets were obtained from the surface elevation of the climate model (https://data.ceda.ac.uk/badc/ukcp18/data/land-rcm/ancil/orog), the Integrated Hydrological Digital Terrain Model (IHDTM; https://www.ceh.ac.uk/services/integrated-hydrological-digital-terrain-model), the Ordnance Survey of Northern Ireland (OSNI) Open Data 50m Digital Terrain Model (https://www.nidirect.gov.uk/articles/50m-digital-terrain-model-height-data), Standardised Annual Average Rainfall 1961-90 (SAAR 61-90; https://catalogue.ceh.ac.uk/documents/51861941-c38d-46e6-9a31-6e9a293fc3d5), the European Space Agency (ESA) GlobAlbedo project albedo (http://globalbedo.org) and UK Energy Technology Support Unit (ETSU) mean wind speeds. Where applied, bias-correction was calculated seasonally using the Climate Hydrology and Ecology research Support System meteorology dataset for Great Britain (CHESS-met; https://doi.org/10.5285/2ab15bf0-ad08-415c-ba64-831168be7293) observation-based dataset. Variables for RCP2.6, RCP4.5 and RCP6.0 were calculated using time-shifting and pattern-scaling of the RCP8.5 scenarios, using selected members of the 5th Coupled Model Intercomparison Project (CMIP5; https://pcmdi.llnl.gov/mips/cmip5) and UKCP18 Global Climate Model Projections for the entire globe (https://catalogue.ceda.ac.uk/uuid/f1a2fc3c120f400396a92f5de84d596a) to determine future warming trajectories.

Data were produced by the project team and supplied for archiving at the Centre for Environmental Data Analysis (CEDA).
