Ever wonder how to adjust in Russia – or what sot of gestures Russian adjusters make when they’re jesting and not jetsetting? Here are Hansen’s urban adjustments for 4 different Russian “urban” sites. In the graphics shown, an upward adjustment in the past is an upward re-statement to increase past temperatures to compare with present […]
I’ve noticed that even Hansen’s rounding seems to give a little edge to modern values relative to older values. It’s not a big effect, but Hansen doesn’t seem to like to leave any scraps on the table. Cara, Siberia has 3 versions – all of which appear to be the same station; all 3 versions […]
A CA reader, John Goetz, has written in with a mind-numbing puzzle related to Waldo in Bagdarin, Siberia, where Waldo appears to have experienced an adjustment unusual even by the standards of NASA chiropractors.
Waldo, Hansen’s ROW trend, is not in Africa nor in Antarctica. Is Waldo in South America?
Waldo (the ROW warm trend) is not in Africa (or the United States). Is Waldo in Antarctica? (For those of you who haven’t bought toys in 30 years, Where’s Waldo is a game.) Antarctica is about 8.9% of the world’s land surface (about 1.5 times the contiguous 48). There are 116 Antarctica sites in the […]
Hansen tells us that he won’t “joust with jesters”, as presumably he’s too busy adjusting to have time for jousting. We by contrast have lots of time to jest with adjusters.
In the discussion of my previous post, a reader posted a link to a fascinating picture of Tucson in 1923 – a picture complete with Stevenson screen in the foreground, if you can imagine, clearly visible on the right. Figure 1. Tucson c. 1923. From left to right: Agriculture Building, Old Main, and the Mines […]
Porto Velho and Londrina are two somewhat similar sized Brazilian cities (populations 335,000 and 500,000 respectively) which have remarkably different Hansen adjustments. One is adjusted up by 2 deg C and one is adjusted down by 2 deg C. It’s pretty strange to see.
Here’s something interesting: I’ve collated the GISS raw(dset=1) and GISS adjusted (dset=2) versions and then calculated the range of adjustments. The largest positive adjustment was over 8 deg C and the largest negative adjustment is greater than -6 deg C. I separated out the stations that had no adjustments (max adjustments under 0.01 deg C […]
I’ve spent some time (an inordinate amount of time) trying to figure out why GISS uses some GHCN stations and not others. Doing so has required a lot of work on GISS data sets which are nastily organized and with many seemingly ad hoc inclusions, exclusions and sloppinesses. Does any of this matter to world […]
