Dear folks,

I believe Ben's suggestion is very good compromise and we should
prepare a Fig. 4 with three RAOBCORE versions, RICH, HadAT and RATPAC.
As I have understood Ben in his first description of Fig. 4, also the
range of model trend profiles should be included.

Who will actually draw the figure? I can do this but I do not have the
model data and I do not have the RATPAC profiles so far. It would be
easiest to remove the Titchner et al. profiles and Steves profiles from
Peter's plot. Or should we send our profile data to you, Ben? What do
you think?

Concerning the possible reaction of Douglass et al.: RAOBCORE v1.2 and
v1.3 are both published in the Haimberger(2007) RAOBCORE paper (where
they were labeled differently). Thus they have at least omitted v1.3.
RAOBCORE v1.4 time series have published in the May 2007 BAMS climate
state of 2006 supplement.

Peter, myself, Dian and probably a few others will meet in Japan by the
End of January and a few weeks later in Germany, where we can discuss
the latest developments and plan the publishing strategy.

Thanks a lot Ben for moderating this Fig. 4 issue.
