OK, what's this?

[rdaniell]

Made an object in SketchUp this morning. These used to be found close to the flight line at one time. Any quesses? First correct answer wins a "NO PRIZE" prize. It is the right size and color for everyone.(The prize)

Weather station?

 

[Mach3DS]

Wind speed and direction equipment.

Hello,
In French : un anémomêtre et une girouette...
It give you the speed and the direction of wind.
In the box, the result are registered... It's right ?
Good flight, serge.

Looks like I'm going to have to get some more "NO PRIZE" prizes. Everyone so far has been correct. It is indeed a satellite weather station. I got the idea from a photo in a book I have on Training Airbases in Georgia during World War II.

Top: Windvane (wind direction)
Below that: Anemometer (wind speed)
Mounted on: A Stevenson screen (a slatted enclosure - usually painted white or silver - that protects various weather instruments such as thermometers, barometers, hygrometers, dewcell, and thermographs)

In short, a weather instrument station...

In character for his Outhouse name: ThinkingManNeil gets credit for the most complete answer. Only problem is that there simply is no grade above A+

Hello,
--" that protects various weather instruments such as thermometers, barometers, hygrometers, dewcell, and thermographs "--

For that instruments, it's nessessary to add the externals probes (if my english is good)...

Good flight, serge.

Inside the Stevenson screen (never did know its official name) shack were two vertically mounted thermometers (mercury in summer, alcohol in winter) one a 'dry' bulb, the other a 'wet' bulb with a wick on the bulb. The idea was to wet the wick and switch on a little electric fan which blew over the wick. This reduced the wet bulb temperature by evaporation. Using the two values - wet, dry, the difference between them and a special circular slide rule (Idiot Wheel), you came up with the dewpoint temperature. Flipping the sliderule over you used the dry bulb temp and the dew point to calculate relative humidity. Working in Alaska, we were 'rewarded' by not having to do this little exercise when the dry bulb was -35 or lower. Many 'spare' dry bulbs were then mounted where they could be read without leaving the warmth. 55 years have passed but the Air Force taught me well.

Well olderndirt, you can thank "Mr. Perfection" for that bit of knowledge. I'm really pleased that this thread which started out because I was bored, has turned into an educational experience for us. Gotta love this bunch of folks at the Outhouse. Thanks guys for all the responses.:salute:

I'll happily defer to olderndirt's knowledge and experience. I used to collect weather data for my senior grade school science class from our school's Stevenson screen but that was a LONG time ago and I'm sure I'd have to undergo some refresher training. Sound's like Dirt's got much more hand's on experience than I did. As I remember, our Stevenson screen had a minimum and maximum thermometer, recording barograph- an old wind-up variety that I had to keep wound and supplied with chart paper - and a wet and dry bulb hygrometer. It had had an anemometer and wind vane but someone vandalized it and broke those off.

Well, here it is installed in FSX with a light hanging above it.

Forgot about the max min's. They were set on inclines and reset every six hours. Our barograph was indoors and compared with the mercurial barometer every six hours. Mcgrath, Alaska - 1959 temp -67, sitting on the teletypes to keep our feet off the cold floor.
