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.
