HadRM3

HadRM3 is the Regional Climate Model (RCM) developed by the Met Office Hadley Centre and used for UKCP09.

In detail

HadRM3 is the Met Office Hadley Centre's regional climate model used to produce regional (~25km resolution) projections of the future climate. 

HadRM3 has been used in UKCP09 to produce 11 runs of regional climate projections at the medium emissions scenario (A1B) on a daily time scale. These 11 runs were used to timescale and downscale the larger ensemble of GCM runs.
