Dear Ben,

This is a good idea. However, will you give only tropical
(20N-20S) results? I urge you to give data for other zones
as well, viz, SH, NH, GL, 0-20N, 20-60N, 60-90N, 0-20S,
20-60S, 60-90S (plus 20N-20S). To have these numbers on
line would be of great benefit to the community. In other
words, although prompted by McIntyre's request, you will
actually be giving something to everyone.

Also, if you can give N3.4 SSTs and SOI data, this would be
an additional huge boon to the community.

For the data, what period will you cover. Although for our
paper we only use data from 1979 onwards, to give data for
the full 20th century runs would be of great benefit to all.
This, of course, raises the issue of drift. Even over 1979
to 1999 some models show appreciable drift. From memory we
did not account for this in our paper -- but it is an
important issue.

This is a lot of work -- but the benefits to the community
would be truly immense.

Finally, I think you need to formally get McIntyre to list
the 47 models that he wants the data for. The current request
is ambiguous -- or, at least, ill defined. I think it is
crucial for McIntyre to state specifically what he wants.
Even if we think we know what he wants, this is not good
enough -- FOIA requests must be clear, complete and
unambiguous. This, after all, is a legal issue, and no court
of law would accept anything less.

Tom.
