date: Tue Aug 9 16:43:39 2005 from: Phil Jones subject: Re: DTR etc to: Kevin Trenberth Kevin, Russ is supposed to be sending the diagrams by the close of his day today. The plot he sent me yesterday for 79-04 for DTR looks better over southern South America. Decisions about infilling and periods of record seem to be important there. Australia looks similar with what Lisa sent (the BoM figure). I've been concentrating on these two regions. Spain is a mix of blue and red. Attaching the plot, dtr at the bottom. Max and then min presumably are the other two. Russ knows exactly what we want, so wait for an email from him in about 4-5 hours time. We should be getting this bottom plot plus max/min/dtr time series from 1950. Paper pdf will likely come later on Wednesday or early Thursday.

Matilde was adamant about S America: I wonder what the reference is? What about Spain? If there are references, then we can opening discuss some differences (and hopefully they can be resolved by next draft). It won't do to have one product that is at odds with some others: that will invite comments. Kevin Phil Jones wrote: Kevin, Russ has only sent me 2-3 emails on this. We've been discussing some of the decisions made on station inclusion. He sent me some revised maps yesterday - of max, min and dtr for the two periods. I reminded him of what we want - dtr map for 79-04 and the time series of max/min/dtr for 50-04. Russ said he hoped to get these plus a pdf by the end of today. His latest DTR trend for 79-04 is -0.001 K/dec. Paper will have trends for the other period and for NH and SH separately.

I haven't been CCing everyone because I didn't want to fill up everyone's in-box with many small messages (I sent 5 just this morning). Kevin Trenberth wrote: Dear Russ and David It is the last few days for our IPCC chapter and we need to resolve the DTR stuff. 1) There was supposed to be an updated Fig 3.2.2 on global time series of max min and DTR. The current one shows a downward drift in DTR although smaller after 1979. 2) What about 3.2.11: this is th map of DTR trends 1979to 2004? 3) What about Vose et al 2005? Vose, R.S., D.R. Easterling, and B. Gleason, 2005a: Maximum and minimum temperature trends for the globe: An update through 2004. Geophys. Res. Lett. (submitted). I still have not seen this and nor has Phil. We need this immediately, if not before. These are now extremely urgent. If the paper is not submitted then we can't refer to it. We have to submit a pdf to TSU by end of the week. And the LAs need to evaluate it. So we can not tolerate any delay at all. Regards Kevin -- **************** Kevin E.
