The UKCP18 web site contains information about the project and the projections, including how to access and use the data and the science behind it.
Q: Are there observational datasets available?
A: Yes, you can find information on them here. These observational datasets can be used alongside the climate model projections. The Met Office’s National Climate Information Centre has produced these at 12km, 25km, and 60km on the Ordnance Survey’s National Grid. The datasets are currently only available via the CEDA Data Catalogue.
Further FAQs will be added to this page over the coming weeks.
