Simon,

I agree that the details of the model runs are open for discussion but the
general level of activity needs to be spelled out to NERC who should be
aware of the extreme inadequacy of HPC provision. We are already hitting
the wall. I'm not proposing that my list of integrations should be in the
RCC documents but they will hopefully aid the discussion on the budget
lines for RCC. I hope you can support me on this because we're working very
hard at the moment with NERC (and DEFRA for that matter) to get improved
HPC provision for climate change.

Julia
