CRUTEM3 stations in Google Earth

I've made KML files for the CRUTEM3 stations. They are on the document store as crutem_kml.zip. If you just extract the files, you'll find two kml files - crutem_all.kml and crutem_recent.kml. The first shows all stations that have reported since 1900, and the second stations that have reported since 2000.

They show up as yellow pushpins - the size indicates the total years in the record. CRUTEM3 stations have longer durations than GHCN - so the largest size is over 90 years, and the smallest under 50. There are, in the inventory, 1943 stations over 90 years, 1198 under 50, out of a total of 5112. This is the count of lines in the record - it overstates the length because there are some years entered in the file with no data. (Update - it seems I was wrong about that - it's not overstated).

If you click on a station a flag pops up with a few more details. Here is a sample view of stations that have reported since 2000:
