Final testing is being done on a supercomputer in Cheyenne that will be used for climate modeling and other Earth sciences.
The new computer, called Yellowstone, is among the top dozen or so fastest supercomputers in the world right now.
An opening ceremony is scheduled for Oct. 15.
The National Center for Atmospheric Research is lining up research projects that will get time on its machine starting this fall.
One project will model air movement inside hurricanes and tornadoes. Another will examine how weather and air quality could change in North America in the years ahead.
