Boulder Scientific Tour Continued
This is in the lobby of the NOAA. It uses ultrasonic vibrations to generate steam from water without heating it, then pumps it up into this large bowl which you can blow down into or run your hands through. It doesn't really serve any scientific purpose, really, but it's fun to play with.
The highlight of the tour for most of us was Science on a Globe. This a six-foot diameter sphere suspended from the ceiling, then four projectors use it as a spherical movie screen to project a globe onto it. This allows presenters to show any array of global information on the sphere, animated. The effect looks exactly what you would expect a hologram of the Earth to look like.
Topo maps.
The night side of the topo map shows the lights that are visible form human activity. Our presenter told us how to recognize the differen types of lights. White are electric lights - cities. Purple lights in the ocean (particularly near Japan) are fishing boats using lights to attract squid to the surface so they can turn them into calamari. Red lights are fires, usually big slash-and-burn operations. Blue lights are oil rig flares.
A view of the globe seeing the tops of the clouds color-coded to show the infrared spectrum. Also, the globe-like head of the kid in front of me apparently trying to simulate an eclipse as seen from beyond the dark side of the moon.
An animation showing the formation of hurricanes in the Atlantic.
The next animation I have is a really cool one showing global warming from the 1870's (as based on ice core samples) and projected into the year 2200 (based on computer models), but the clip is bigger than the Vox limit of 50 megs. When I get back home I'll see if I can work it into a smaller file. All of the other videos I took were also over 50 megs. Hmmph!
After Science on a Sphere, the tour took us into a conference room where one of their employees demonstrated on a big screen the NOAA's experimental island in Second Life. It looked neat, but unfortunately my bandwidth at home just can't handle Second Life.
After leaving the NOAA, we went to the National Center for Atmospheric Research. It was a much shorter tour and there wasn't nearly as much to see, but their building was neat, and they had a very basic science museum just inside the door.
The building was designed by architect I. M. Pei after visiting Mesa Verde National Park.
A view of the Flatirons Mountains from right outside the NCAR facilities.
Some door archways on the exterior of the NCAR facility. For comparison, here is a shot I took at Chaco Canyon National Historic Park:
Another view of the Flatirons.
Back inside the NCAR facility, a mural showing the different altitudes where various atmospheric phenomena exist. From this mural, I learned about a type of cloud that I hadn't heard of before: noctilucent clouds. They are much higher in the atmosphere that other cloud formations, and as such they can sometimes reflect light from the sun back down toward the night side of the planet, making them appear to glow. I wonder how many UFO sightings such clouds have caused. They're also interesting because scientists don't yet understand how clouds can form at such high altitudes or why we're seeing them in lower latitudes in the last couple of decades than we used to.
An early air sampler rocket, meant to take samples of air at high altitudes. This one was used at the White Sands Missile Range.
Finally, since we're going white water rafting Sunday and we forgot to pack hats to protect us from the sun, I bought a couple of floppy fishing hats at the NCAR gift store for Strix and me.
Yes, my face really is that round. Sad, huh?
It's time for lunch. More later!
