The UK Climate Projections are based on a new methodology designed by the Met Office, which allows a measure of the uncertainty in future climate projections to be included in the information.
UKCP09 is the fifth generation of climate information for the UK, and is the most comprehensive package produced to date. For the first time it provides probabilistic projections of climate change based on quantification of the known sources of uncertainty.
Along with the UKCP09 website a User Interface has been provided to facilitate access to the projections; User Guidance is available to support decisions related to using UKCP09. To support users in exploring potential impacts, vulnerabilities and adaptation options, UKCP09 also offers two analytical tools - a weather generator and a supportive threshold detector.
More information about the UK Climate Projections is available on the UKCP website
