    Kevin,
         I'll broach it with the UK people. Need to consider timing in November, once we
    get the comments or maybe after the ChCh meeting.  Been to Boulder in Jan and Feb
    before so know what to expect ! Early Feb would seem best. Not thought about
    going to the AMS so won't.
        A few problems with Figures today. Hopefully they will get resolved in the not too
    distant future.  Dave E has at least sent one email.
       Seeing our granddaughter on Saturday, but should have some good time for
    the Chapter on Sunday and Monday (at home).
    Cheers
    Phil

     Hi Phil
     I am attaching the updated Fig 3.4.? I have also in .ps that can be converted if need
     be.
     Dennis has also plotted the Fu data and I'll send a version a bit later.  But need to
     have consistent colors.
     I am encouraged that the text is getting a lot better.  The FOD is approaching close to
     what will be final, we should find.  After that point the figs should only be updates
     and minor changes, and the text is modified to respond to comments, that we will have to
     address more systematically next time.  The SOD does become close to final: still
     subject to all the reviews and late breaking material.
     Key thing is for you and me to make sure we converge, and don't do a wholesale
     replacement of a section without careful checking.
     I have decided not to attend AMS AGM next year in January so that I can work on the
     SOD.  I would be glad to invite you to come for a visit for a week and I suspect we can
     also come up with some funds to help: at the price of a seminar.  e.g. we could split it
     by you doing airfare and we do local accommodation or vice versa?  This summer Tom
     Stocker is here and working with Jerry on chap 10.  I think it could be worthwhile, main
     question is best timing.  Perhaps late Jan or early Feb?  That time of year can be cold
     here: usually not that much snow or if it does snow it does not last long in Boulder:
     great skiing nearby if you are interested in that.  Mean T in Jan is about 0C but highs
     not uncommon about 10C, and have been over 20C with chinook.  Cold at night.  So good
     idea.
     Cheers

      Kevin,
         Things seem to be coming in.  Will work on 3.5-3.7 tomorrow. 3.2 and the Appendices
      now back with David. The Appendices read pretty good - lots of useful background
      material. It will be shame to lose it to a web site. Once David gets these back these
      should be almost good enough to go out to all on July 15 (or whenever we said).
         A thought kept recurring - there must be a better way to do this !  Although the FOD
      reviews will be different from the ZOD (and many more), I'm prepared to come to Boulder
     for a week
      in early 2006 if needed. I think I can get the money from the UK to do this. Question
     is
      will be it be worthwhile. Better if we were both locked away somewhere other than one
      of our institutions, but then we wouldn't have the infrastructure, support (email,
     printers
      etc).
         Anyway, give it some thought. You'll know more than I do about some much the FOD
      and SOD change. Q is whether a week or a fortnight is sufficient.  If we knew that a
     few of the
      key people in the chapter were at their desks, the text should show a marked
     improvement.
      Assuming here the majority of the Figures set by then - just a few need updating.
      Cheers

     Hi Phil
     Thanks for update:  monday is a holiday here: Memorial Day, seems weird that Brian is
     working?
     My approach to the revisions at this stage is not to take the material sent and
     wholesale replace it, but cautiously compare and insert if it makes sense.  i.e. you and
     I need to act as editors with a fairly strong hand.  I suspect 3.7 may have some useful
     material but it could degrade the section by further adding material that is not
     especially relevant.  I'll bet it does not shorten it, which is desired still.
     I am clearly not on same page as Brian wrt clouds and radiation, and I am interested in
     his take on it all, given the new material and changes.  I am not a fan of Norris'
     stuff.  We have updated Fig 3.4.1 on water vapor thru 2004: the ocean trend drops to
     1.2%/decade.  So you can help a lot by putting your take on the 3.4 stuff: it may also
     require some careful wording to accommodate different views if we can't see eye to eye.
     For instance, on the dimming, the recent Pinker paper uses ISCCP and I simply don't
     believe the trends from ISCCP at all.  Saying Wielicki and ISCCP agree actually damns
     them both.  Or similarly saying Norris and ISCCP agree causes problems (this relates to
     upper cloud, which Norris gets from total minus lower, but those two sets of data are
     not homogeneous: there is not a lower cloud ob for every total; using means, esp zonal
     means without differencing each ob potentially causes major problems).
     Dennis is starting on the 3.6 figs today plus the Sahel one.
     Cheers
     Kevin
