Steve Goddard and Anthony Watt have a series of posts on an old favorite topic on this site — how data manipulations back in the climate office is creating a lot of the “measured” warming. This particular example is right here in Arizona, and features several sites my son and I surveyed for Anthony’s site. They have a followup on another Arizona station here. Check out all the asphalt:
This is a hilariously bad siting. It demonstrates how small things can sometimes have big effects. The MMTS sensor has a very limited cable length. This does not mean that it only comes with a short cable (begging the question of why they can’t just buy a longer one), but that it can only have a short cable due to signal amplification issues. As a result, we get this terrible siting because it needs to be close to the building, whereas even a hundred yards away there were much better locations
Carefree is a fairly rural (at least suburban) low density town with lots of undeveloped land. They had to work to get a siting this bad. A monkey throwing darts at a map of the area would have gotten a better siting.
