The NOAA website http://mi3.ncdc.noaa.gov/mi3qry/search.cfm? has a Map tab linking to local maps and Google Earth. I don’t recall seeing it before. Maybe someone can comment on this and also check the accuracy of the maps for stations shown there.
I was looking to see if their equipment reporting included whether stations had aspirated or unaspirated housings. In the old CDIAC forms, the form of housing was recorded and perhaps it is here as well (if so, I’d appreciate info on how to find it if anyone knows.)
