Case studies and demonstration projects
On the case studies and demonstration projects page you can explore UKCP-related case studies and demonstration projects showing examples of how people have used UK Climate Projections datasets.
Factsheets on UKCP products
We have produced a series of short documents, which summarise the key results for a number of UKCP18 variables and metrics. These can be found on our dedicated Factsheets page.
Guidance on using UKCP
A number of peer-reviewed guidance was produced in the development of the UK Climate Projections. Their purpose is to provide information for those analysing UKCP datasets:
- Data availability, access and formats (PDF - 1.5MB) [Updated April 2021] where you can find out what data is available for download and how you can access it.
- Representative Concentration Pathways (PDF - 259kB) where you can find out more about what they are and how we use them in the climate projections.
- Caveats and limitations (PDF - 787kB) which details issues that you need to be aware of when using UKCP datasets.
- How to use the different sets of Land Projections (PDF - 1.8MB). This guidance document helps you choose the set of projections that meets your needs.
- Bias-correction (PDF - 809kB). There are systematic differences between model results and observations (i.e. “biases”). When carrying out your analysis you will likely need to choose whether to adjust the climate data for these biases. The method chosen can be very specific to the application. This guide helps you make informed choices about bias correction methods.

Technical notes
A series of technical notes clarifying particular questions and issues about the UK Climate Projections.
- Clipping and baseline advice on Land Strand 1 data in UKCP18 (PDF - 1.1MB). This note covers characteristics of the probabilistic projections data, such as clipping at extreme ends of the distributions and non-zero sum of anomalies during the baseline period.
- The elicitation of distributions of parameters in HadGEM3 versions GA4 and GA7 for use in perturbed parameter ensembles. This note provides more detail about the perturbed parameter set of global projections.
