Many of you have followed my “how not to measure temperature” series showing many examples of the folly of thermometer placement in the USHCN network. But what about the rest of the world?
One of the most important things we look for is finding weather stations that are as far away as possible from human influence, so that they can resolve the “climate signal” unhindered and without need for retroactive data adjustments.
Weather stations on a remote mountaintop would seem to be a good candidate. Fred Harwood writes to me with one such example of a remote mountain station: Pointe Helbronner, Mont Blanc in the Alps, near the France/Italy border at 3462 meters high, about 11,358 feet.
Fred trekked to the top, to get this photo for us:
The temperature sensor is properly mounted inside the round louvered white radiation screen on the left side of the mast. The remote weather station also has a live webcam, as you can see in the photo (inverted glass dome) You can see a live webcam of this view here:
The latest image is a few days ago, so there may be a transmission problem.
The remoteness of such a station surely is impressive. Getting an accurate temperature measurement devoid of human influence would almost certainly be guaranteed, and we would not have to worry about nearby objects, people or buildings at such a remote location.
Well, maybe not….
And you can see more of the station and how it is situated (on the roof of a building) here in this YouTube video:
I suppose I’m not surprised. I’ll point out that this likely is not an official climate station. I don’t see it listed in GISS or NCDC. But the point remains, why go to all the trouble of a research quality temperature shield if you put the temperature sensor on a rooftop within reach of tourists? I’m sure that wood has an albedo of consequence and dozens of tourists also create a warm air pocket.
