Warren Meyer, one of the first surfacestations.org volunteers, delivered Tucson today. You may remember from the “Red and Blue States” thread on CA that Tucson had the greatest positive temperature trend for any USHCN station after TOBS adjustment. I’ve been trying to find the words to describe this station, but the pictures really do a better job than I ever could.
They are so proud of this station they even had a sign made for it to hang on the chain link fence enclosure:
Besides the obvious questions like “why is it in the middle of a parking lot?” and “why would scientists who should know better allow such a bizarre siting for a USHCN climate station of record?” Then there is this burning question: “Why did they go to the trouble of installing a precision aspirated temperature sensor and then not even bother to place it at the standard observing height?”.
It appears that the Stevenson Screen serves no other purpose except as an equipment holder, as Warren reports the Stevenson Screen to be empty. Originally the standard mounting boards for the mercury max/min thermometers were mounted about 1.5 foot higher than the air inlet of the precision aspirated temperature sensor. So the lower mounting height for the precision sensor adds a positive bias.
Is there no diligence left in basic measurement?
