In a breakthrough that will help scientists unlock mysteries of the Sun and its impacts on Earth, an international team of scientists from NCAR and the Max Planck Institute for Solar System Research has created the first-ever comprehensive computer model of sunspots.

The stretch of the subcontinent that runs from eastern Pakistan across northern India into Bangladesh is likely the world's most intensively irrigated region. A new NCAR study shows that between 2002 and 2008, the region depleted groundwater at a rate of around 13 cubic miles per year.

Arctic temperatures in the 1990s reached their warmest level of any decade in at least 2,000 years, new research indicates.

Along with unusually persistent rains, there was a different kind of watery surprise this summer for people on the U.S. Atlantic coast. From the barrier islands of the Southeast to the rocky shores of Maine, tides ran as high as 2 feet above predicted values.

A team of NCAR researchers led by Jacob Fugal is developing and testing a specialized instrument that uses digital holography to measure tiny cloud droplets.
