Anthony Watts, Evan Jones and the numerous outstanding volunteers have provided us with an effective, land breaking documentati0n of the quality of siting of surface observations that are used in the construction of the US Historical Climate Network. Anthony reported on this topic in the outstanding report:
Watts, A. 2009: Is the U.S. Surface Temperature Record Reliable? 28 pages, March 2009 The Heartland Institute.
Anthony’s research as led to our first joint paper on this subject

On December 12 2006 I posted examples of photographs of observing sites outside of the USA in the post
Over the next few weeks, I will post the photographs that appear on that site as well as others that I am able to find. I encourage readers of my weblog to e-mail me information on other sites which I can post on the weblog. There is also a need to identify which of the posted sites are GHCN locations. This, hopefully, is a first step to extend Anthony’s analysis world wide. While these stations do not have the photographs from each cardinal direction, they are still very useful.
The first three stations are the following:
Footnote: For all of its flaws, the USHCN has one big advantage over the ROW and GHCN – superior metadata. That said, even then it is difficult to find stations sometimes. For example yesterday I made a road trip to fix a station survey that had been identified as being at the airport in NCDC…except that it wasn’t anywhere near the airport. More on that later.
The locations of most of the worldwide GHCN stations are not well documented in metadata, and lat/lon values published are so coarse that it makes spotting one from Google Earth nearly impossible. That said, documenting the state of the GHCN is going to be an uphill challenge.
