However in his second paper Watts has used a different methodology. As Watts explains:
Previous papers all used a distance only rating system from Leroy 1999, to gauge the impact of heat sinks and sources near thermometers. Leroy 2010 shows that method to be effective for siting new stations, such as was done by NCDC adopting Leroy 1999 methods with their Climate Reference Network (CRN) in 2002 but ineffective at retroactive siting evaluation.
Leroy 2010 adds one simple but effective physical metric; surface area of the heat sinks/sources within the thermometer viewshed to quantify the total heat dissipation effect.
This new Leroy methodology enables UHIE to be more accurately accounted for and has allowed Watts to find large warming biases in the official temperature networks.

The effect of UHIE is well known to science; even NASA accepts the UHIE. Temperature data, therefore, which may be affected by UHIE, needs to be carefully adjusted. In a comparison between Watts and Muller it is Watts who seems to be doing this better and producing more accurate science.
The comparison between Watts and Muller goes to the heart of the AGW debate and the angst shown by elites like Manne. Watts is not an academic; he is just a meteorologist without a string of degrees. Watts is an ordinary person of the sort Manne and his superior ilk would like to muzzle via Finkelstein and Hamilton. At the end of the day though, it is often not the self-appointed elites but the Watts of the world who do not have the resources and financial support, who produce the goods. By ignoring the worth and value of people like Watts, Manne and the AGW elitists have proven that they are the real deniers. Pretty ordinary, really. Where is Wayne Swan and the Boss when you need them?
