Inspired by the cliff dwellings at Mesa Verde National Park, I. M. Pei designed this striking pink-sandstone building, which overlooks Boulder from high atop Table Mesa in the southwestern foothills. (You might recognize the center from Woody Allen’s “Sleeper,” as some scenes were shot here.) World-class scientists study such important phenomena as the greenhouse effect, wind shear, and ozone depletion to gain a better understanding of the earth’s atmosphere. Among the technological tools on display are satellites, weather balloons, interactive computer monitors, robots, and supercomputers that can simulate the world’s climate. There are also hands-on, weather-oriented exhibits and a theater. Outside, the Walter Orr Roberts Weather Trail takes visitors on a .4-mile, wheelchair-accessible loop along a path with interpretive signs describing various aspects of weather and climate plus the plants and animals of the area. The center also houses a changing art exhibit and a cafeteria. Allow 1 to 2 hours.
