In 2006, a team of NCAR researchers convened in Mexico City for MIRAGE, a study of the chemical and physical transformation of air pollution in urban areas and its impact on air quality, ecosystems, and climate. Another MIRAGE field campaign kicks off this month, this time in Shanghai, China's largest city.

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.

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.

A new study led by NCAR scientist David Edwards is the first to apply the concept of Observing System Simulation Experiments to chemical weather (predicting pollution events and variability in the atmosphere’s chemical composition).

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 researchers are studying whether the eruption of Indonesia’s Mt. Toba supervolcano about 70,000–75,000 years ago may have cooled Earth enough to initiate an ice age and potentially alter the course of human evolution.

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.

One of the challenges for global climate modelers is accurately simulating cloud cover and its changes over time. This is vital for projecting future temperatures, rainfall, and other aspects of global and regional climate change.

Using a highly efficient modeling technique, Pablo Ortiz (University of Granada) and Piotr Smolarkiewicz (ESSL/MMM) have simulated the role of winds in forming sand dunes and sandholes.

NCAR researchers are looking at how new generations of super-fast Graphical Processing Units (GPUs) and multicore chips, such as the Cell Broadband Engine, can be used in atmospheric models.
