"How not to measure temperature, part 34"

Check out the latest from Anthony Watts here.

Excerpts:

Klamath Falls was one of those places where you have to wonder “what were they thinking?” when they placed a climate monitoring station. Imagine measuring the temperature in the middle of acres of asphalt combined with huge amounts of waste heat from electric power conversion. That’s’ Klamath Falls USHCN official climate station of record.
...
Can you imagine the heat from the transformers being transported by wind, or the heat from the massive asphalt in the service staging facility yard being pushed toward the sensor by the wind? Being almost exactly in the middle of the complex, it’s hard to imagine any bias free day there, wind or not. It’s a likely scenario, and one well suited for a study this coming summer where I may ask permission to place a sensor at the old measurement location, and position some temperature loggers around the facility to quantify the difference.

Another thing this location may have been doing in the long term is measuring waste heat generated by the transformers as a function of power usage demands. Historically, power use has not declined, so its safe to assume that this facility, its transformers, and capacity has been upgraded over the years to handle increased demand.

Yet we measure temperature there...
