   By the way, Phil, we (Tom Smith, Dick Reynolds, Jay Lawrimore and I) are in the process of
   revising our global temperature number approach.  We've added in satellite data over the
   ocean.  This tends to slightly cool 1998 and a couple other years, but 1998 the most (all
   the differences are in the Pacific  40-60 degrees S).  We treat buoys and ships
   differently. As the buoys are reading colder than ships (which was first pointed out by the
   Hadley Centre I believe) this warms the recent record as more and more buoys come on-line.
   It looks like it will be a couple months before we have this all operational and completely
   tested and ready to make it public.  The skeptics aren't going to like it one bit so we're
   making sure we have all our ducks and tests lined up and ready to show that this is,
   indeed, a better process and why.  We've also improved the earlier record by using
   different size boxes and cut offs for when to use data and when not to which cools 1880
   somewhat compared to our previous version, again with objective tests that clearly indicate
   why this is better.  Just thought I'd give you a heads up on it.

      Haedline might be.  2006 no longer warmest year over the lower 48 states.
      It is now 1998, but we just missed it at the time!
      I presume you'll have error bars and good explanations!
      Cheers

      Dear All,

             Occasionally I get to the end of a week and have a little spare
      time. I then look at Real Climate and Climate Audit. Look at the
      link above and the story about the USHCN.  I began to look at
      the comments and said to myself - how long will it be before the CRU
      data are dragged into this. Answer - not long!
         What Brohan et al were getting at was the issue you know well.
      Country X or Scientist Y sends some data - saying its been homogenized.
      We added this data to the database as it looks fine (after some checks).
      Most of the data were for new stations. They may or may not contain
      adjustments but we use them, and we don't have the raw data, just what
      we've been sent!
         I bet you'll get many more accusations of manipulating the data. The
      skeptics don't seem to want to accept that techniques get better and new
      ideas come along.
      Cheers
      Phil
