They say “imitation is the sincerest form of flattery”, so color me flattered. I’ve been remiss in writing about this effort by Roger Tattersall (aka Tallbloke) and his colleague Tim Channon, but a tip from WUWT reader David Schofield brought me to think this would be good to mention it, so they can make comparisons. First, as you may know, they have an ongoing effort to catalog UK surface measurement stations. Details here.
They are using the Leroy 2010 methods as I use in Watts et al 2012, for example here.
A recent post talks about 20 UK CLIMAT stations, which are used to report to GHCN. It might be interesting to see where those stations are located in relation to this:
This is an official output from the UK DECC website called “The National Heatmap”:

The plot is generated by turning on layers using the interface. TB’s stations that he has surveyed could easily be added since this is a Google Earth product. All he has to do is get the source data from DECC. Or, some manual overlays could be tried.
Given the recent paper highlighted on WUWT about heat density/UHI in China versus surface temperature, this would seem to be a good exercise.
Here’s a closeup of London, showing the heat map along with power station locations plotted.
The station that got all this started with an errant temperature, Gravesend, is east of London along the Thames. I theorized then that that Thames itself might be a source of heat for that station, and given the density of power plants along it shown above, there might be some truth to that theory.

Look at the location located by Tim Channon:
That spit of land juts into the Thames. If the Thames is warmed by power plant cooling outlets putting out waste heat upstream, I would think this station is getting a huge dose of the heat seen in the national heat map.
