From Tom Nelson
[Tom Karl, Director of the National Climatic Data Center] We are getting blogged all over for a cover-up of poor global station and US stations we use. They claim NCDC is in a scandal by not providing observer’s addresses. In any case Anthony Watts has photographed about 350 stations and finds using our criteria that about 15% are acceptable. I am trying to get some our folks to develop a method to switchover to using the CRN sites, at least in the USA.

Note this email, because it will be something I reference in the future. – Anthony
Thanks for watching over all of this...working on my computer system again....things are in a bit of disarray.....

1.) The new USHCN2 sites are all COOP, not a CRN site among them. That leads to the question of what the raw CRN data is (gridded and ungridded) and why the suggestion to convert to CRN readings was not implemented.
2.) After the substitution, there are 2218 USHCN2 sites as compared with 1221 USHCN1 sites. By my count, 50 have been added, 53 discontinued. This has had the effect of somewhat increasing the adjusted historical trend by ~0.12C/century. This increase may be due to the change in stations, a change in adjustment, both (or perhaps some other factor entirely).
Heh-heh
They just freely admitted their weather stations are crap.

evanmjones says:
Wow.
Yet he does not seem to have switched over to CRN.
At this date we have surveyed well over a thousand stations (I, myself, have over 200 kills, a dozen f-t-f, the rest “virtual” and/or by direct interview). Most of the remaining USHCN1 stations are long closed, and some sites are known only after recent station relocations).
The recent switchover to USHCN2, substituting ~50 stations, does not, to my recollection, show a switchover to CRN stations — but I will give it a look-see and report back.
Also, UHCN1 showed a +0.6°C/century trend, while USHCN2 shows +0.72. But that’s adjusted data, of course. As NOAA has refused to release its adjustment code, we cannot reproduce the adjusted data, and therefore, of course, any results are Scientifically Insignificant.)

Those E-Mails are really revealing all of the machinations....

Brilliant! I bet reading that for the first time felt a bit like pay day!
Off topic, but here in the UK we’re experiencing heavy snowfall up and down the country.
Here from the Press Association:
“Forecaster Paul Mott, of Meteo Group, the weather division of the Press Association, said the deep freeze was likely to continue into next week meaning the snow is likely to settle and much of Britain will remain carpeted in white.”
Until just a few hours ago, the Met (as reported by the BBC) was predicting “light snow” for tonight. Double “Heh!”
These people are the most incompetent and corrupt "scientists" I've ever encountered.

@ Roger Sowell
Siting is only part of the problem. The type and style of instrumentation changed several times over the period of interest, and corrections to the data are then made because the data produced is discontinuous. In principle this should not be necessary, but it is, and typically the corrections are poorly applied. Anthony has meade several postings comparing various generations of instruments, and the differeces in them.

Seems that way to me!

Just goes to show how threatened these people feel. Call me suspicious, but if they had nothing to hide I would have expected more than just this frightened capitulation.
Anthony, this is a BIG win for you and your team. Thanks again for all the hard work put in.

Thanks to Anthony and Climategate 1 & 2 the intransigent people (warmer’s) have sat up and noticed, they circled the wagons to no avail, in military terms they have been fighting a classic rearguard action with a steady but quickening retreat. These email or the poor ground station sitings are nothing new to readers at WUWT, but a sad commentary on the sordid state of so called climate science and the political crass class. How can any disciple of the church of global warming defend the indefensible is a mystery to me!
Thanks again Anthony for you tireless battle to expose these charlatans.
Anthony Watts is my hero. WUWT and FR are the two sites that I go to daily.

I have surveyed (and submitted) one hard-to-reach weather station. I would not have known what to look for without the information in this blog over the past years. The problems I saw that can influence the measurements from just this one site made concrete what has been said here. How can anyone grounded in the scientific method believe that the world’s temperature has increased by 0.1 C (or whatever) due to readings from these places? Thanks Anthony and Evan!
Same here!
fyi
An admission that the ground-based data is garbage.
Yet this was a 2007 email. To the best of my knowledge, nothing was changed over the past 5 years.
See some of the comments to the article I apended to the thread.
The exposé on the weather stations was when I first discovered WUWT. It’s gratifying to find out they’re at least paying attention to the skeptics — even if they’re not actually doing anything.
Who's got guts for global warming debate?
