Online climate change projections report 5 Ensemble of RCMs

This chapter describes data from an ensemble of eleven variants of the Met Office Regional Climate Model (HadRM3), run from 1950–2099 and used to dynamically downscale global climate model (GCM) results as part of the UKCP09 methodology. The daily RCM time series are not included as a UKCP09 product, and are therefore not accessible via the User Interface. However, RCM daily data may have advantages over that from the UKCP09 Weather Generator for some impacts studies, and is the only 25 km resolution data available over the seas around the UK, so has therefore been made available via the Climate Impacts LINK project. We describe here the RCM data, the advantages it may have for some users, and also its limitations — the main one being that it does not cover such a wide range of uncertainty as the UKCP09 probabilistic projections.
