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.

NCAR has teamed with the Inter-American Development Bank (IDB) to launch a far-reaching program to help Latin American and Caribbean nations prepare for the impacts of global warming.

Close to 9 out of 10 adult Americans obtain weather forecasts regularly, and they do so more than three times each day on average, according to a new nationwide survey.

In a breakthrough that will help scientists unlock mysteries of the Sun and its impacts on Earth, an international team of scientists led by NCAR has created the first-ever comprehensive computer model of sunspots.
