Flagstaff in Coconino County, Arizona — The American Mountains (Southwest)
Clark Dome Weather Station
Instruments for the station were enclosed in an instrument shelter, which shielded thermometers, hygrometers (to monitor humidity), and other devices from the Sun, precipitation, and other sources of heat and light that could produce inaccurate readings. This type of shelter features downward-pointing louvers that allow for air flow while shielding the instruments from heat and light.
This weather station was removed in the latter part of the 20th century, but a modern station is now mounted on top of the Clark Telescope dome. Can you see it? Look for the anemometer (for detecting wind speed), whose wind cups may be spinning.
