Study sponsored by NOAA finds that poorly-sited air temperature monitoring stations have artificially boosted global warming data

American Thinker’s Thomas Lifson brings attention to poorly-sited air temperature monitoring stations that have artificially boosted global warming data:

Anthony Watts of Watts Up With That reports on an important scientific paper sponsored by the National Oceanic and Atmospheric Administration (the official keepers of temperature records) that confirms what Watts and other critics have maintained for years. To its credit, NOAA decided in 2012 to test Watts’s critique that a substantial portion of the surface air temperature monitoring stations that are used to generate data for claims of global warming are located in places that have become surrounded by urbanization in the form of asphalt and concrete surfaces and other facilities that absorb heat during the day and discharge it at night — thereby artificially raising the average air temperatures…

As a scientist, Watts uses the scientific and technical terminology but explains it. For example:

I have published on the topic in the scientific literature, and found this to be true based on the science we’ve done of examining the USHCN and applying the siting methodology of Leroy 2010.

In Fall et al, 2011 we discovered that there was a change to the diurnal temperature range (DTR). It decreased where stations had been encroached upon, because of the heat sink effect of man-made materials (asphalt, concrete, bricks, etc.) that were near stations.

For layman readers that don’t know what diurnal variation is, it is the daily variation of temperature due to the variation of incoming solar radiation from rotation of the earth on its axis.

Lo and behold, the scientific paper promised in 2012 has been published and it confirms the critique. The language is technical, but the results make common sense and confirm that claims of global warming have been inflated:
