Mosher shooting himself in both feet, good and bad.
“B.) The sampling is FINE if anything its over sampled. That is
why you can for example pick 110 PRISTINE sites in the US
(CRN) and predict the rest of the country: Including
100s of other pristine sites ( RCRN) and 1000’s of “bad” sites.
What’s it tell you when you can start with 60 samples and get
one time series… then add 300 and get the same,,, then add
3000 and get the same…. then add 30000 and get the same?
whats that tell you about sampling?
Whats it tell you when you can pick 5000 and then predict any
other 5000 or 10000?”
What it tells anyone with common sense is that all the sites have been linked to each other by an algorithm and are no longer individual raw or individual site modified data but data that has been homogenized to fit in with every adjacent site.
This is not something to be proud of.
This is scientifically very, very wrong.
Any true set of recordings makes allowance for the fact that temperatures very from minute to minute from site to site and that due to known weather variations sites do not have to match each other in step.
What Mosher alludes to is pure chicanery.
Any set of sample sites that agrees this perfectly means they are not real temperature recordings anyway in any form.
It is the Cowtan and Way Kriging experience over again.
You must be able to pick sites that do not agree with each other in any sample.
That is what weather temperature, measurement is all about.
When you link everything to each other so they all move in step whatever sample you take you do not have real measurements.
Try it on the raw data Steven. See if they all move the same way whether you use 2 or 50,000.
I will guarantee they don’t.
Take your modified data and prove they all link perfectly.
I guarantee they do as well. I have your word for it.
And what do you call your data?
Well not data anymore.
“E) Accuracy is a vague term.”
No it is a very accurate term
“for example pick 110 PRISTINE sites in the US
(CRN) and predict the rest of the country
you can for example 1000’s of “bad” sites.”
So in your system bad sites are just as accurate as pristine sites.
That alone makes none of them pristine any longer and all of them bad.
