SubjectRe: CRUTEM4
Phil,

I can't believe that people think it remotely reasonable behaviour to
send that sort of crud. They'd never say that to your face. I guess
their home is just that much more cosy and impersonal.

Cash would need spending in FY09/10 as I understand it, but someone for
six months (assuming they could start this Sept.) could be a route
forwards. It would be a good paper for them career-wise.

HadSST3 is in first draft form. I'm not sure what papers you assume will
arise. I think we were thinking of developing HadSST3 and CRUTEM4
seperately (but in a joined up way) and publishing as separate papers
and then doing a paper that covers combination to HadCRUT4 and perhaps,
for example, a d&a sensitivity to error model assumptions.
