And finally, the satellite data was not very helpful unless there was a rawinsonde sounding nearby to anchor the information.
You can see the effects of desert summer heating quite clearly when viewing a sonding from one of the high desert rawinsonde stations in California.
Taking either pi-ball or rawinsonde soundings of the atmospheric thicknesses between say 850b and 700mb should reflect the kind of radical warming that Mann et als claim.
Part of the problem back then was they way the models interpolated the atmosphere between rawinsonde stations.
Another thing that has bothered me with the Mann’s temperature spike during the last 50 years of the 20th century, is the lack of supporting data with relation to what has been reported via surface an rawinsonde data.
