Ed,
A few thoughts.
1. For surface T (and SST separately) we have the concept of the
effective # of spatial degrees of freedom (as especially for SST)
T changes slowly. I'll attach our latest surface T paper (just submitted)
and an earlier one. This concept might be useful, wrt errors in the
various types of obs.
I can see why most people try to take the base period out. We've
tried to allow for the error of estimation of this as well. It is likely
much easier for the surface as there are many more obs.
2. Is there a period for the 0.06 and 0.037 deg C increase? Presumbly
it is since about 1950?
3. The Soon et al (2004) paper referred to on p3 is missing from
the refs. Do you have a pdf of this? If it is Willie Soon, I'd be very
doubtful about it being much use. He tends to be economical with
the truth to suit his own ends!
4. Paper should be a useful addition to Ch 5 on oceans.
Cheers
Phil

Ed,
I'll get to this the week after next. The next IPCC draft has to be in
this Friday, then I have a week off !
Have you sent this draft to the convening lead authors of the ocean chapter?
They are from memory Nathan Bindoff and Jurgen Willebrand.
Syd is an LA on the chapter.
I'm on Atmospheric Obs. with Kevin Trenberth. There are separate
chapters this time for oceans, cryopshere and paleo.
Cheers

Hi Phil
My student and I have gotten together a ms on the upper ocean temperature trend project
we've been at.
We're at a bit of a loss to understand how Levitus and others have gotten the results
they have...it appears that they've had to resort to a great deal of extrapolation.
I've attached a preprint here, in case it might be of interest to you.
Comments are always welcome.
I hope your summer is going well.
All best wishes,
Ed
