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. Tom P. Phil Jones wrote the following on 2/16/2007 7:46 AM: 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 Phil [1]http://www.climateaudit.org/ 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.
