France – 2009 Temperature Stations

E.M.Smith
"What Do We Actually Measure in France Today? - In a prior posting we found that there are all of 17 stations in France in 2009 that are used by the GHCN. The overall dT/dt graph was produced (using all historical data in GHCN) and that made a great “hockey stick”. With gently dropping temperatures turned into a rapid rise at the end.A brief inspection of the station list show that it was almost all Airports. Only one station was not flagged as an airport (and a commenter stated that it was, in fact, an airport too).So we surmised that putting all the thermometers at the Airports would cause much of the observed temperature rise (that ‘just happens’ to start right after the non-airports are dropped from the series…)But it nagged at me that I’d not looked at these stations in depth. Was it possible there were some turly great stations here, asking to be contrasted with others? Would there be rampant indications of Tarmac Attack in the record? Just what did those temperatures look like? Well, I’ve finally gotten the set done. Now we will see."
