I guess my point is that while the data for the troposphere showed cooling before the known correction, scientists were putting faith in the models even though the data showed different.

And attempting to "regularize" data based on a simple weighting algorithm is not very accurate whatsoever.

"I defer to your expertise."

I am only a software engineer developing simple algorithms and doing seismic system design. But "regularization" of data is a big big issue in the seismic field and we have PhDs and double-PhDs working around the clock on algorithms. A weighting scheme is a very basic and not so good method for spatial interpolation and extrapolation.

And that's a very good point.
