How not to measure temperature, part 14

It is the US Historical Climatological Network (USHCN) Station of Record for Hopkinsville, KY. The NOAA provided Max/Min Temperature Sensor is located at the observers home. The nearby air conditioner is just 10 feet from the temperature sensor. Then there’s the chimney. The contribution of the portable BBQ grill to the temperature record is unknown.

The MMTS temperature sensor wasn’t always mounted on the tower next to the house, it used to be in the yard, but the observer made some “improvements” over time. Note that published NOAA/NWS siting standards require a 100 foot distance from buildings.

  1. I wonder if he had the AGW crowd in mind? …

    “There is one feature I notice that is generally missing in ‘cargo cult science’… It’s a kind of scientific integrity, a principle of scientific thought that corresponds to a kind of utter honesty, a kind of leaning over backwards… For example, if you’re doing an experiment, you should report everything that you think might make it invalid, not only what you think is right about it… Details that could throw doubt on your interpretation must be given, if you know them.” – Richard Feynman

  2. I’m sure that concrete slab won’t have any effect on the sensor either.

    Nice antenna tower, though.

  3. Hey, Anthony, quite a nice mention about you and your project on the Rush Limbaugh show this AM…Congrats!
