GHCN - European Mediterranean Migration
The European Thermometers are abandoning the Boreal, Continental, and Atlantic zones (or perhaps, the Steppic), and headed for the Mediterranean Beaches. (Who’ wouldn’t!) But hanging in there in the Arctic and Alpine. Maybe they like to ski and swim, but not farm?
UPDATE 11/3/2009: I’ve added an “experimental” by Altitude chart at the bottom.
Europe, the Temperature History in GHCN
We start with one thermometer in the 1709 decade ending. There is the typical spread to other latitudes, reaching good coverage about 1900. There is a bit of wobble in the WWI and WWII interval, though surprisingly little, then the migration to the “below 45 N” group of bands begins in ernest.
This is the usual South Pole on the left, North Pole on the right.
What does Europe look like? The decade changes by latitude look like this:

A very striking example of The March Of The Thermometers.
This trend by definition must span multiple countries, multiple geographies, multiple climate zones, and multiple governmental agencies (especially given the many decades involved and the somewhat ‘fluid’ nature of governments in Europe… I see no particular moment in time nor latitude on which to focus. This, as they say, will take some pondering. You can ponder too…
The Country Temperature Series
Same as the others. Year, 12 monthly averages of the daily MIN-MAX average, the average of those daily values over the whole year, and the number of thermometer locations (ignoring modification flag) in use in that year.

Well, that’s a little bit more helpful. There is a bit of a step function in the 1960 era. We see the (now) typical 1990 +/- thermometer deletions, a one year drop out in 1995 (was there some war or governmental collapse then?), followed by the (also ever more familiar) addition of a few in the 2008 range. Anyone want to lay odds that the “adds” are more on the warm side and not up in the snowy mountains?
The December, January, February, March months get a significant ‘lift’ from those changes. Somehow the winters are warmed; but July and August stay flat. It must be a move to ocean moderation, but from where and to where? Digging through 300 thermometer records is not something that can be done on a web page. It will also take more time than I have tonight; so that particular mystery will have to wait. But we can put up a nice “Dig Here!” sign…
In Conclusion
We have an extreme and prolonged example of thermometer migration over time. I’m at a loss to imagine why. All the countries are fairly densely populated. They all have decent science institutions. And I’d expect them all to have a well instrumented weather system. Perhaps it is just a GHCN thing, or perhaps not. There is a large, but somewhat low urgency, “dig here”.
I suspect it has something to do with the “European Russia” part, country code 638. Perhaps it was Hadley losing their data… If we look at the temperatures without European Russia it is flatter, but not by much.

But at the end of it all, I’m left with a bit of a puzzlement about the hows and whys of the European March Of The Thermometers to the Mediterranean. I can see it happen, but can’t see why… What I can say is that the temperature data seem to have more of a “step function” flavor to them then a “regular progression” effect, even thought the latitude changes are general and gradual.
Perhaps, given all the microclimates and mountains, it simply takes a finer comb to look through the exact changes.
I think I need to write a new bit of code. A program to sort the thermometers into bins, by latitude and by altitude, and look at the pattern of changes of those bins over time. I would expect all the thermometers in a similar bin of altitude and latitude to sit still over time. It would be fairly easy code to write.
But for now, I’ve done a marathon run to push out “The Globe” in temperatures and lattitudes, and I think I’m going to take a break for a bit. Recharge, and come back to the problem fresh in a couple of days.
UPDATE 11/3/2009
Well, I got up this morning and, cup of tea in hand, made a new toy. I’ve just done my very first 2 test runs with it, and it is not QA verified at all so strictly experimental at this point, but I felt like giving it a debut anyway.
This is a “By Altitude” chart for Europe. If I find any bugs as I’m shaking down this code, I’ll change the chart here, probably without notice. Like I said, this is the real time experimental stuff…

Percent of thermometers by Altitude in meters based on the first altitude measure in the v2.inv file (there are two…). The thermometers run up the mountains starting in the late 1700s and into the mid 1800s, then they fade from the 200 meter band to the sea level after WWII. Don’t know that it means anything yet.
But ‘it went “zip” when it moved and “bop” when it stopped’ and I found that amusing so I wanted to share:
Just to let you know, I think this is fantastic work you’re doing.
This is the “climate” work worthy of a Nobel — real work in the real world. Seeing and telling it as it is. Providing data and methods for falsiability. Transparency and accountability. Great work.
This is an incredible body of work.
