But, Alastair, as you may recall, the S & C work with the MSU data was
shown to be in error several times over. And, IMHO, the S & C MSU/
AMSU results are STILL WRONG! You may not be aware of it, but the UAH
TLT includes coverage from locations over the Antarctic, which is well
known to include a rather large component of surface effects. The
team at RSS decided to exclude data poleward of 70S, as well as
locations with high mountains. The RSS TLT trend has shown a greater
warming trend, up until a year or so ago. The RSS team did not
include the AMSU data (although they may now), whereas S & C do.
These discussions have been going on for more than a decade and you
apparently think the S & C TLT results are superior to the other data
sources. Perhaps you, like John Christy, simply want to wave a magic
hand over the data and simply assert the UAH product to be the best,
as he and Douglass did in their new E & E paper. But, did it ever
occur to you that the UAH TLT is the result of modeling, starting with
the derivation of their original algorithm? The recent UAH TLT
includes the AMSU data by modeling the MSU algorithm. Aren't we
simply going around and round arguing over which model is best? If
one looks at the error bars, these data tend to be in general
agreement, last I heard...
