Urban Sites Dominate US Temperature Record
By Paul Homewood
From the “It’s Raining Today, So I’m Just Playing With Some Numbers” Dept!
On the GISS website, they have a full list of the stations they use, in turn supplied by the GHCN website. I would stress that this does not necessarily mean they are all currently live, but the list includes details on the Brightness Index, and also whether the station is airport based.
From this we can glean the following. (The Brightness Index runs from 0=Dark to 256 = Bright; GISS regard 10 and under as being “rural”)
| Total | Airport | Non Airport | |
| Rural | 598 | 204 | 394 |
| Urban | 1306 | 547 | 759 |
| Total | 1904 | 751 | 1153 |
In other words, only 394 out of 1904 stations can be regarded as unaffected by UHI influences, a ratio of 20.7%.
Again, I would emphasise that not all of these stations are currently live, though, if I had to guess, more rural sites would have dropped than airport and urban sites over the years. Nevertheless, it raises considerable doubt over the reliability of the US temperature record.

NOT A LOT OF PEOPLE KNOW THAT 
If those ”monitoring station” are not EVENLY distributed; instead each one represents referent size ares = they are completely useless. Pacific covers 1/3 of the planet, with only 3 thermometers, that’s a joke – would be thrown out of court, before it gets to grown up people
