High Resolution Global Environmental Model runs

HiGEM (High Resolution Global Environmental Modelling) is a UK programme in between NERC (Natural Environment Research Council) and the Hadley Centre of the Met Office. The aim is to advance in the fidelity of simulations of the global environment by taking the new Met Office climate model (HadGEM1a) to unprecedented resolutions. The resulting simulations aim to improve our understanding of mechanisms of climate variability and change on timescales of days to centuries.

HadCM3(L30) data are held as 64 bit UM fields files HadCM3 control data are held as 32 bit pp files HadCM3 control data from the Beowulf cluster are held as NetCDF files HadCEML data held as both NetCDF and pp files.
