  1. Connecting the upper and lower atmosphere

    An experimental modeling study by a team of scientists that includes NCAR’s Hanli Liu (High Altitude Observatory) points to the propagation of waves upward from the lower atmosphere as a driver for variability in the ionosphere. The research is an important step toward better understanding space weather.

  3. Searching for Sun-like stars with satellites and supercomputers

    Travis Metcalfe, NCAR's High Altitude Observatory • How common are planets like Earth around other stars like the Sun? Are we unique, rare, or typical in that regard? Metcalfe likes asking big questions.

  4. Analyzing asteroseismic data from the Kepler mission

    A new technique developed at NCAR will help asteroseismologists learn about stars from their oscillations, or “starquakes.” These variations in the brightness of stars reveal information about their internal structures.

  5. WACCM goes to new heights

    NCAR scientists are working on a bigger, bolder version of WACCM (the Whole Atmosphere Community Climate Model), called WACCM-eXtension, or WACCM-X for short. The enhanced version extends the model to an altitude of about 310 miles.
