You yanks are surly thinking! I wonder if Al Gore has the brain cells to ponder the thoughts discussed here? For the sake of all Irishmen will you please keep him in his castle and not let him out!

A wee bit on Brad he is great fellow.

“As an engineer I would say there is no way to correct the data from this site to account for the various problems. The only solution is to exclude it from the database. That brings me to my question; is there a plan to determine the US temperature record using only stations rated 1 or 2?”

Like the Rev says.

But That’s ony 63 stations! (And a mere 19 of them are CRN1. (A good MMTS is hard to find. Another quandary for Demosthenes.)

On top of that, there’s a westward bias (and the west is where most of the actual warming did occur).

REPLY: I suspect we’ll find more CRN1/2 stations in the midwest, in the middle of the plains. For now though, most of the area is under snow, and not many new stations are being surveyed. When the summer travel season picks up again, so will surveys.

Has anybody ever looked at Cleveland Ohio? talk about a discontinuous record.

REPLY: yes there is, but we need to fill in missing areas first so that we get better spatial representivity. See the map on the main page of http://www.surfacestations.org

That’s gotta be a CRN5, then, doesn’t it? Heat sinks and waste heat within 10 feet and all.

REPLY: It could go either way as a 4 or a 5, but without measurments, I can’t say for certain

For what ever it is worth, I agree with the additional findings regarding that ecru building. I am satisfied that it is not, you should pardon the expression, cold storage, but some kind of electrically active equipment room. and the auto start warning would be required for A/C condensers, air compressors, engine-driven power plants, … which can be summarized as “warm stuff”.

My comment appears to have been eaten by the spam filter, but here is a repeat:
More then likely that “storage unit” is a back up communications power unit for the fire department. Below the Halogen sign is one reading:

Caution:
Lead Acid batteries …
Corrosive liquid …
Energized Electrical Circuits …

Most probably a heat source with those warnings. Transformer, charger, electronics.

“Quick! Somebody create an adjustment equation.”

Quick and dirty.

THE WATTS ADJUSTMENT

Low: (%CRN1*0)+(%CRN2*0)+(%CRN3*1)+(%CRN4*2)+(%CRN5*5)
Medium: (%CRN1*0)+(%CRN2*0.25)+(%CRN3*1.5)+(%CRN4*3)+(%CRN5*7.5)
High: (%CRN1*0)+(%CRN2*0.5)+(%CRN3*2)+(%CRN4*4)+(%CRN5*10)

Results to be expressed in “Revs”, representing offsets in degrees C.

Those familiar with this site will know instantly what I mean.

%CRN1-5 = Percentage of CRN1 through CRN5 ratings for surface stations.

Of course, there’s only one way to check. (I take it you got my email, Rev?)

“which cautions against automatic equipment which may start at any time.”

That is probably a backup power generator for the electronics shelter which would start up automatically when mains power fails.

Even worse it’s on the south facing slope, on the north side of the road. Much more scrubby, less forested than the south side, IIRC. Talk about a micro climate …

Ah, yes, I forgot: “Click for larger images”. Thanks, Anthony. When I do, I can see the electric power drop to the top of the wooden pole behind the building, and Larry, that’s a flag, not a wind sock. I can also read some of the placards in the larger images, one cautioning that the building is protected with a Halon fire suppression system, indicating a large amount of expensive electronics inside. That antenna is not complex enough for a cell site, however, so it must be telephone stuff. The most intersting placard is the one way in the back corner, on the retaining timbers, which cautions against automatic equipment which may start at any time. Implying something with exposed moving parts and just maybe produces some heat? And, the rain gauge is protected against wetness only from some directions.
