It has been well known for years that having a thermometer at an airport, a true heat island, is a farcical way to measure the temperature. in the area.



A study that investigated the placement of National Oceanic and Atmospheric Administration (NOAA) temperature stations found that 96 percent of the facilities used to measure heat failed to meet the agency’s own “uncorrupted placement” standards.

Research for the study shows the 96 percent corruption is because the stations’ measurements are tainted by the effects of urbanization – or heat produced because of their close proximity to asphalt, machinery, and other heat-producing, heat-trapping, or heat-accentuating objects.

The Heartland Institute compiled the report using satellite and in-person surveys of NOAA weather stations that contribute to the “official” land temperatures in the United States.

“With a 96 percent warm-bias in U.S. temperature measurements, it is impossible to use any statistical methods to derive an accurate climate trend for the U.S.” Heartland Institute Senior Fellow Anthony Watts, who directed the study, said is the study announcement distributed to the press. “Data from the stations that have not been corrupted by faulty placement show a rate of warming in the United States reduced by almost half compared to all stations.”

“NOAA’s ‘Requirements and Standards for [National Weather Service] Climate Observations‘ instructs that temperature data instruments must be “over level terrain (earth or sod) typical of the area around the station and at least 100 feet from any extensive concrete or paved surface,’” the press release said. “And that ‘all attempts will be made to avoid areas where rough terrain or air drainage are proven to result in non-representative temperature data.’

Yup. They only use around 1600 of the 7500 or so weather stations, and the ones that they do use are sited in crap locations.

Yeah - I've talked to an MIT engineer about this, and they say the data's been wrong for decades.
