Should we spend $45 trillion based on data collected like this?

How not to measure temperature, part 74 « Watts Up With That?
For those of you that don’t know, this station is located at the wastewater treatment plant there. I’ve written many times about the placement of stations at WWTP’s being a bad idea due to the localized heat bubble that is created due to all the effluent coming though. The effect is especially noticeable in winter. Often you’ll see steam/water vapor in the air around these sites in winter, and more than one COOP observer has told our volunteers that snow sometimes does not stick to the ground at WWTP’s.

The larger pole appears to be a gas burnoff torch for excess methane. I can’t say how often it is activated (note the automatic ignitor circuit on the pole) but I can tell you that putting an official NOAA climate thermometer within a few feet of such a device is one of the worst examples of thoughtless station placement on the part of NOAA I’ve ever seen.
