That’s really just human nature, if oversight isn’t diligent. The guy did the best he could within reason and in the context of what was actually expected of him. Now tink about the same guy way out in Siberia in the winter in the 1930s. The 1980s. Or Central or East Africa

Mr. McIntyre and all:
I’m a newbie to this thread, but I have seen other reports of the “thumb on the Butcher’s scale” about lowering of Siberian temperatures in the days of the ‘land of 13 time zones (colin Powell’s) starting with the late John Daly. Does anyone know of an original, probably Russian cite or English translation of such by somebocy “who was there or who has first hand or scholary knowlege of actual lowering of observed temps for “survival: purposes.

That was quick. The last 11 years of data certainly modifies any 20thC trends. It begs the question as to the source of the adjusted USHCN data. Does the relative geographic proximity to the other hot spot play a role? Does teleconnection occur through the adjustment process in this case?

Here is a plot of the Hallock data. There have been no measurements there since 1996. “Adjusted” USHCN data is plugged for the last 11 years!

The coatings slightly increase the radiational insulating effect of the bare wood. The temp changes are “forced” from outside the box (radiational), so the wood is colder (night) or warmer (day) than the thermometer itself.

I don’t know if the temp differences are enough to significantly affect the thermometer readings tho.

I can, but can’t promise how soon I might get there… Very interesting.

It looks like the station is at the
Municipal Airport plus there appears to be a water treatment site nearby. Anybody know anything more? Hallock according to is an unlikely site for any UHI effects, but clearly there is a chance for micro-site effects.

By the way the report makes fascinating reading. The authors appear to be somewhat guarded in their acceptance of AGW. They also seemed to have been engaged in a similar station by station analysis of other States. Are they still active in the field?

I think I follow. Looking forward to the Stevenson Screen tests.

Remember I’m measuring the temperature of a solid, not of a gas. I expect this is caused by IR emanating from the solid (wood slats) causing a cooling, much like IR from the ground on a clear night will chill the ground, and air near the surface to form fog.
