The data are projected extreme sea levels at approximately 2 km spacing around the UK coastline, including England, Wales, Scotland, Northern Ireland, and Isle of Man. The data were produced by the Met Office, using estimates of present-day extreme sea levels at all open-coast Coastal Flood Boundary point locations, provided by the Environment Agency and projections of exploratory extended time-mean sea level change prepared at the Met Office. Projected extreme sea level values are described for 16 different annual probabilities of exceedance (return levels), ranging from 1:1 to 1:10,000, identified in the shapefile as ‘t1’ to ‘t10000’. Confidence levels relating to the 5% and 95% lower and upper bounds of confidence are included, identified in the shapefile with the prefix ‘c1_’ and ‘c3_’ respectively, as well as the 70% confidence level identified in the shapefile with the prefix ‘c2_’. The data were produced to put the projected future mean sea level change in the context of the present-day extremes. The data were produced by combining the best estimates of present-day extreme sea levels with projections of mean sea level change. The data covers the period from 2020 to 2300 and is available for each decade (i.e., 2020, 2030... 2300). Further information on this dataset and UKCP18 can be found in the documentation section.

5km gridded resolution data for four climate projection scenarios, produced in support of the UK Climate Impacts Programme 2002 (UKCIP02) by the Met Office Hadley Centre. There are data for monthly and seasonal average anomalies with respect to simulated 1961~90 average for four alternative future climates for the UK. The four emissions scenarios are Low (LO), Medium-Low (ML), Medium-High (MH) and High (HI). Monthly data for cloud, precipitation (prec), temperature (temp), maximum temperature (tmax), minimum temperature (tmin) and wind are available using the following convention in the filename: 2020s = predictions for 2011 to 2040, 2050s = predictions for 2041 to 2070, 2080s = predictions for 2071 to 2100.

The 5km temperature time-series data for four climate projection scenarios produced in support of the UK Climate Impacts Programme 2002 (UKCIP02). Monthly temperature time-series data for four alternative future climates for the UK. The four emissions scenarios are Low (LO), Medium-Low (ML), Medium-High (MH) and High (HI).

The 50km gridded resolution data for four climate projection scenarios produced in support of the UK Climate Impacts Programme 2002 (UKCIP02). There are data for monthly and seasonal average anomalies with respect to simulated 1961~90 average for four alternative future climates for the UK. The four emissions scenarios are Low (LO), Medium-Low (ML), Medium-High (MH) and High (HI). The monthly time-slice data are available for the following variables: Maximum temperature (TMAX), Minimum temperature (TMIN), Daily mean temperature (TEMP), Total precipitation rate (PREC), Snowfall rate (SNOW), Wind speed (WIND), Relative humidity (RHUM), Total cloud in longwave radiation (TCLW), Net surface longwave flux (NSLW), Net surface shortwave flux (NSSW), Total downward surface shortwave flux (DSWF), Soil moisture content (SMOI), Mean sea level pressure (MSLP), Surface latent heat flux (SLHF), Specific humidity (SPHU), Inter-annual variability: temperature (IAVT) and Inter-annual variability: precipitation (IAVP). The data are available over the following time periods using the following convention in the filename: 6190 = 1961 to 1990, i.e. observed climate, 2020s = predictions for 2011 to 2040, 2050s = predictions for 2041 to 2070, 2080s = predictions for 2071 to 2100.

Time-mean Sea Level Projections for the UK produced by the Met Office for UK Climate Projections 2018 (UKCP2018). Data has been produced by standard and exploratory methods.

Climate model runs at convection-permitting scale for the UK for three time slices (1981-2000, 2021-2040, 2061-2080) produced by the Met Office for UK Climate Projections. The data is available on a 2.2km grid on a rotated pole at various temporal resolutions: hourly (for some variables), 3-hourly (for some variables), daily and longer averages. Additionally, the data has been regridded onto a 5km grid on the Ordnance Survey's British National Grid. Note that these data 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 Project News page: https://www.metoffice.gov.uk/research/approach/collaboration/ukcp/ukcp18-project-news/index. The previous version of the data will be retained on CEDA for twelve months until 21st July 2022.

Derived climate model projections data produced as part of the UK Climate Projections 2018 (UKCP18) project. The data produced by the UK Met Office Hadley Centre provides information on changes in 21st century climate for the UK helping to inform adaptation to a changing climate. The derived climate model projections are estimated using a methodology based on time shift and other statistical approaches applied to a set of 28 projections comprising of 15 coupled simulations produced by the Met Office Hadley Centre, and 13 coupled simulations from CMIP5. The derived climate model projections exist for the RCP2.6 emissions scenario and for 2°C and 4°C global warming above pre-industrial levels.
