The change currently is from .135K/decade global trend to
..128K/decade. In the future this change will underreport
warming. There are many interpretations of satellite microwave
sounding unit, or MSU, data, this team at the University of Alabama,
Huntsville, UAH, produces one that shows less warming
that the others.

I'll leave it to those who do such things to document the
connections between Spencer an Christy and the Carbon
fuel industry.

Yet Another Spencer and Christy MSU Version?

Update 9 Sept 2006 *****************************

We are nearing completion of the new diurnal corrections and
the conversion of AMSU data to mimic MSU data (rather than
substituting AMSU5 for MSU2, as in v5.2). We will likely use a
statistical combination of AMSU4-9 to generate a more
realistic MSU2 from which LT and MT are derived. This will
make the time series more consistent.

The diurnal drift and hot target effects of NOAA-15 and
NOAA-16 render the recent months of v5.2 too warm since
we haven't adjusted for those effects. As a quick solution,
we are subsituting a preliminary version of LT (v6.0p)
for Jan - Aug 2006 for which these adjustments have been
applied. We caution that there are still likely to be some
changes to v6.0 when it is released in a month or two, but
this seemed the best path to take given the growing errors
especially in NOAA-15 LT. The remaining months prior to Jan 2006
will be v5.2 as before, so we will still label those months as
v5.2. When we have completed v6.0, we will relabel all of the
datasets accordingly.
