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.

The derived climate model projections are provided on a 60km spatial grid for the UK region and the projections consist of time series for the RCP2.6 emissions scenario that cover 1900-2100 and a 50 year time series for each of the global warming levels.

This dataset contains realisations scenario with global warming stabilised at 4°C

This dataset was generated by the computation detailed below.

UKCP18 Derived Climate Projections for a 4°C global warming level on a 60km grid of the UK


This dataset was produced using an emulation technique. The technique is based on applying the time shift methodology to the UKCP18 Global Climate Projections, along with some other statistical techniques, to produce time series of climate variables for the UK region only. Each realisation provides an example of climate variability in a changing climate. The dataset cover the time period of 50 years and comprises of monthly time series of near surface air temperature, precipitation rate, relative humidity, near surface wind, northward near surface wind speed, eastward near surface wind speed and net surface short wave flux. Daily time series of near surface temperature and precipitation also exist. Since not all realisations in the UKCP18 Global Climate Projections reach a global warming of 4°C above pre-industrial levels, there are less than 28 realisations in this dataset.
