Now some, not Eli of course, have had their fun with Willard Tony, but Eli has always been serious and respectful (oh yeah, well this one was early days). OTOH there are, to be sure, problems with his approach, his papers and his all around understanding of what he is doing, many of which surfaced with what Roger Pielke the Elder called the major game changing paper in the history of the world, and
NigelSteve called crap
Over at the Weasel's, Evan Jones is proclaiming that all is well and fixed. Well, young Eli asks, what do you find, and Evan says

4.) We find that Tmean trend for compliant (i.e., Class 1\2 stations using Leroy 2010 proximity ratings) stations is fully 0.11C lower than that of poorly sited stations (Class 3\4\5). This includes consideration for both TOBS and MMTS.
5.) Unless LeRoy 2010 is wrong in a manner which reflects on our use of it or unless our ratings are incorrect (or both), our findings are consistent with the hypothesis that stations with poor sitings not only have higher readings, per se, but significantly higher trends as well.
6.) Stations with both good microsite and mesosite warm at a rate of approximately half their NOAA-adjusted trends, which, in turn, coincide with the adjusted trends for poorly sited stations.
7.) Therefore US ground surface temperature is exaggerated by that amount of difference.Far be it from your humble bunny to throw a spanner into the wheels of progress, but this is EXACTLY what you would expect from the Dr. Who Effect (TM E Rabett). As Eli pointed out back in the year dot, taking pictures of surface stations today (or in 2009) tells you nothing about the condition of the stations in 1980 or 1950 or whatever, without a functioning time machine.
Watt and Jones classify stations based on recent condition. If the condition were the same in 1980 or 1950 or whatever, this would yield (with TOBS correction, etc.) a valid trend.
What about stations that were, let us say worse, in 1980, 1950 or whatever, why assuming as they do that measured temperatures for class 3-5 stations are higher, then the trend will be lower. The Dr. Who Effect which lowers any trend in the Class 1/2 today stations.
