It's worth noting that the results from Mears et al. at RSS shows stronger
warming in the tropics than does the latest UAH computations.

Mears et. al. write:

"In the Northern extratropics, there is excellent
agreement between the Christy et al. results and a
sub sample of the radiosonde sites chosen to
have consistent instrumentation type and thus
thought to be relatively free of error (Christy,
Spencer et al. 2000). Presumably the agreement
between these radiosondes and our data would be
somewhat worse, though this has not been tested
here."

Pretty much what I've been saying, and waiting for,
for quite some time.

That's "extratropics" not the tropics, which is the latitudes where the
differences between the MSU and sonde data resulted in controversy. As
Prabhakara pointed out back in 2000, the monthly data is dominated by short
term variation and thus the trend is a small part (about 5%) of the variance.
There could easily be "good agreement" between the sonde data and BOTH the UAH
and RSS products for the Northern extratropics, while they differ in their
respective global trends.
