UK Climate Projections 2018 (UKCP18) Convection-Permitting Model (CPM) and Empirical Copula modelled widespread rainfall events for 1980-2000, 2020-2040 and 206
A set of ~72000 summaries of mainland GB peak daily rainfall data describing widespread rainfall events as modelled using UKCP18 meteorological data (using a convection permitting model) based on RCP8.5 for 12 members of a perturbed parameter ensemble. ~34000 come directly from the CPM outputs, and a further 36000 (1000 events per ensemble member per time period) generated using an Empirical Beta Copula approach. This was generated for three periods: December 1980 to November 2000, December 2020

Useful for
- Use cases llm-inferred
- Climate-change uplift check on widespread peak daily rainfall for FRA/surface water risk, comparing 1980-2000 baseline with 2020-2040 and 2060-2080 · Extreme rainfall event inputs for drainage strategy sensitivity testing · Stochastic widespread-event sample for catchment-scale flood risk analysis
- Audience llm-inferred
- flood risk consultants · drainage engineers · hydrologists · climate change risk analysts
Limitations
- Constraints llm-inferred
- Summaries of widespread events only, not full gridded CPM output · About half the events (~36000) are statistically simulated via Empirical Beta Copula, not direct model output · RCP8.5 scenario only · Scripted access needs a personal access token
