Ken--Here is a comment back from John Mitchell on the US review of Ch 6. Guess it was my comment that got him most stirred about data release. I will reply and try to ease off a bit--and will see him in Asheville next week. You might otherwise want to reply.

Dear Mike,

it was good to see you in Boulder. I think you organized an excellent session.

I have just received and glanced through the US comments on IPCC95 chapter 6,
section 2. For the most part, they are very helpful and will, I beleive,
help me improve the text. Please thank those who obviously took some time
and care in reviewing the text. I think we can accomodate most of the specific

comments.

I did have some difficulty with the general comments. It was not

clear from the specific comments what instances there were of "disconnected
sentences.... not always logically related to one another". Nor am I quite
clear to what extent we can provide a discussion of model results and what
they mean" where we have done so we seem to have got our wrists slapped eg
interpreting the degree to which flux correction per se distorts the
response of

models. I would be grateful for guidance on this before next week when I will
go over the section in detail before the Ashville meeting.

As regards unpublished results, we have included references to results
which should be submitted for publication well before the publication date of
the report. Given the slow rate of turnround of referees at present (perhaps
exacerbated by their involvement in IPCC) some will inevitably not be accepted
by next January.

I should also like to rebutt the innuendo about release of results.
The only request for information that I am aware of being refused is Pat
Michaels request to me for grid point data from the model. I supplied him
with copies of the relevant manuscript which I believe fulfills the US
wish that detailed information should be generally available for all model
results cited in the report". This view is supported by the fact
that none of the 700 or so other reviewers have requested gridpoint data.
Thank you again for the care you have taken in assessing the chapter.
With Best wishes

John

Dear Mike,

I hear through Richard Moss that my refusal to give Pat Michaels
grid point data will be considered by a congressional Inquiry.

This seems rather odd, as Pat has written I respect your decision, although
I do not agree with it. Perhaps you can let me know what the situation is.
Note that the data does not belong to IPCC, it belongs to Her Majesty's
Government. Will you be at the IPCC meeting in Madrid?

With best wishes

John
