Sorry, that's not my understanding. (I've had a side chat with the NERC 
higem folks about this). I  *do* think the only definition of institution 
that makes sense is those responsible for managing the information 
within CMIP5 (which in many cases, but not all, will be the same as 
those who ran the simulations).

The MOHC is responsible for whatever they want to be responsible for. 
If, for example, as is likely, the Oxford folks want to bring along 
ClimatePrediction.net runs, they'll be HadCM3 but the institution will 
probalby be Oxford.

It looks like the institution for HiGEM will be NERC, and the model name 
will be HiGEM-1-2, but with the definition of NERC exploding out into a 
list of institutions ... beyond NERC alone.
