Again, as we’ve seen time and time again, the placement is not often about the best location, it is about convenience for the observer.

Uhm, manual reading the temp between two huge pools of feces? You call that convenience?

Anthony,
Some days I can screw up the simplest of things.

Just before the Clinton #1 graph you wrote

“A nearby station, 25km away, Clinton, IL, is also in the GISS database and shows less of a trend during the same period:”

Should say…
A nearby station, 25km away, Clinton, IA, is also in the GISS database and shows less of a trend during the same period:

REPLY: Fixed, thanks

Pierre,

The grating is 6+ feet from the Stephenson Screen. Look at the other pictures, for a side view. http://gallery.surfacestations.org/main.php?g2_itemId=39035

Anthony,

Clinton is on the Mississippi.
Clinton is listed in Iowa, yet is measured from the PO in IL (in your spreadsheet).
NOTE —Clinton, IL. is about a third of the way down the state, near but south of Bloomington, IL.

REPLY: It is not a USHCN station, but a GISS station and the nearest to Morrison. See this list of nearby stations within a 200km radius of Morrison:

All this reminds me of an episode of Gilligan’s Island. Season 2, episode 6, called “Quick Before it Sinks”, “The professor mistakenly believes that the island is sinking”.

The professor was using a stick in the water (to measure water level). Gilligan was using the stick to anchor a fish trap, and started moving the measurement-stick to deeper water (to catch bigger fish). Very funny…

Could you redo the first graph so they have the same vertical scale? That would make it easier for me to compare them. It is obvious to me that 1998 is different, but I am not so sure of the others. — John M Reynolds

REPLY: Talk to GISS, that what they output. I find it annoying as well.

This really stinks,no pun intended but it shows why some data is questionable.

Addendum to my previous post on the temperature variances between O’Hare, Palwaukee field, and my house.

The distance between O’Hare and Palwaukee is ~8.8 miles due north as the birdie flys.

The distance between O’Hare and my house is ~15.4 miles NNE as the birdie flys

The distance between Palwaukee and my house is ~8.9 miles NE as the birdie flys.

Are there any photos or specs of/for the Clinton station? Is it near anything?

On a similar vein, I’ve been watching the hourly readings from both O’Hare and Palwaukee fields in Illinois (using my handi dandy Storm Predator software) for some time now. I’ve been also recording measurements taken from three sources around my home including two from different LaCrosse weather stations and one from a clinical thermometer designed for chemistry applications.

Although the readings from my abode and Palwaukee are generally in sync, the O’Hare reading varies greatly depending on wind speed and direction. At first I was puzzled by the large, seemingly random variance.

But then I noticed that when the wind was from the east it would bring Lake Michigan’s cool temperatures over my area, but apparently mixes that same cool air mixes with Chicago’s hot urban air (especially when the city council is in session ) and decidedly impacts the temperatures by the time they reach O’Hare. At least that’s my theory so far.

Are there any photos/specs posted on the O’Hare location?

This is especially bad. Much worse than near asphalt. A parking lot may increase in usage, and thus temperature, over time. But a water treatment plant certainly will. You should see both more heat and humidity emitted and both more energy absorbed and trapped.

Global warming may well be caused by an increase in hot showers by teenagers.

Wait a second… are you saying this data is CRAP? =) Sorry, couldn’t resist.

Looking at the photos, what the heck is that grating under the station?
And I always wondered about what kind of material is used for the roof of the Stevenson screen. Is it plastic, metal, wood…? Especially in the summer the material for (and condition of) the roof could have a significant positive heating bias.
