Mike,
Only have it in the pdf form. FYI ONLY - don't pass on. Relevant paras are the last
2 in section 4 on p13. As I said it is worded carefully due to Adrian knowing Eugenia
for years. He knows the're wrong, but he succumbed to her almost pleading with him
to tone it down as it might affect her proposals in the future !
I didn't say any of this, so be careful how you use it - if at all. Keep quiet also
that you have the pdf.
The attachment is a very good paper - I've been pushing Adrian over the last weeks
to get it submitted to JGR or J. Climate. The main results are great for CRU and also
for ERA-40. The basic message is clear - you have to put enough surface and sonde
obs into a model to produce Reanalyses. The jumps when the data input change stand
out so clearly. NCEP does many odd things also around sea ice and over snow and ice.
The other paper by MM is just garbage - as you knew. De Freitas again. Pielke is also
losing all credibility as well by replying to the mad Finn as well - frequently as I see
it.
I can't see either of these papers being in the next IPCC report. Kevin and I will keep
them
out somehow - even if we have to redefine what the peer-review literature is !
Cheers
Phil
Mike,
For your interest, there is an ECMWF ERA-40 Report coming out soon, which
shows that Kalnay and Cai are wrong. It isn't that strongly worded as the first author
is a personal friend of Eugenia. The result is rather hidden in the middle of the report.
It isn't peer review, but a slimmed down version will go to a journal. KC are wrong
because
the difference between NCEP and real surface temps (CRU) over eastern N. America doesn't
happen with ERA-40. ERA-40 assimilates surface temps (which NCEP didn't) and doing
this makes the agreement with CRU better. Also ERA-40's trends in the lower atmosphere
are all physically consistent where NCEP's are not - over eastern US.

I can send if you want, but it won't be out as a report for a couple of months.
Cheers
Phil
