Steven Mosher has been a big advocate of using KML files to pass location data for stations into Google Earth. I'm planning to add KML file output to TempLS. But in the meantime, as a follow-up to the previous post, I've made KML files for the GHCN and GSOD databases, if you want to look more closely at them in Google Earth.
The files are on the docs repository. They are in a zipfile called KMLfiles.zip, and are called GHCN.kml and GSOD.kml. You can read them into Google Earth either by just clicking on the filename in a file browser (GE pops up), or by using Open or Ctrl-O in GE. These files just read in the stations as a whole lot of placemarks and names- there's no tour provided.
Here's a snapshot of where you would start:
