NCAR researchers are increasingly adopting an innovative tool for statistical computing and graphics. Called R, this community software project is the statistics equivalent of the LINUX movement.

Preliminary research at NCAR suggests that biological particles may contribute significantly to the mass of organic carbon stored in atmospheric aerosols. The study is an important step for scientists.

When it comes to global air pollution, what goes around comes around. Air pollution from factories, traffic, and power plants in Asia wafts over the Pacific Ocean to the United States, while pollutants produced in the United States wind up in Europe.

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.

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).
