Also, why do the only two groups using satellite data to measure atmospheric temperature disagree with themselves and each other on what temperature they are measuring?
They use differing algorithms petal.
Of course those that don't do satellite data rely on use the Reynolds
Reconstructed Sea Surface Temperature. And according to Phil Jones CRU the normals for the SST in the Southern hemisphere were mostly made up.
"Tom,
The issue Ray alludes to is that in addition to the issue
of many more drifters providing measurements over the last
5-10 years, the measurements are coming in from places where
we didn't have much ship data in the past. For much of the SH
between 40 and 60S the normals are mostly made up as there is
very little ship data there.
Whatever causes the divergence in your plot it is down to
the ocean.
You could try doing an additional plot. Download from
the CRU web site the series for SH land. It doesn't matter if
is from CRUTEM3 or CRUTEM3v (the former would be better). If that
still has the divergence, then it is the oceans causing the
problem.
What you're seeing is too rapid to be real. Cheers
Phil"
Dated 2009.
http://di2.nu/foia/foia2011/mail/2729.txtSo no real data until about 2000. And yet you pin your faith to temperature reconstructions going back to 1880 or in some cases 1850. Of course there would be even less data from 40S to 85S. Bizarre.
