Scientists working to crack key air quality and climate mysteries in U.S. Southeast

Scientists working to crack key air quality and climate mysteries in U.S. Southeast

Scientists this summer are taking one of the most detailed looks ever at the natural and manmade emissions that affect air quality in the Southeast, and their movement and chemical transformations within the atmosphere. The mission should help scientists determine the origin of the fine particles and how they contribute to the haziness in the region and affect regional air quality and temperature trends.

Los Angeles air pollution declining, losing its sting

Los Angeles air pollution declining, losing its sting

The cleanup of California’s tailpipe emissions over the last few decades has not only reduced ozone pollution in the Los Angeles area, it has also altered the pollution chemistry in the atmosphere, making the eye-stinging “organic nitrate” component of air pollution plummet, according to a new study.

Mystery solved: "Extra” methane in LA's air traced to fossil-fuel sources

Mystery solved: "Extra” methane in LA's air traced to fossil-fuel sources

A new study, led by NOAA and its Cooperative Institute for Research in Environmental Sciences at the University of Colorado Boulder, used a novel approach to trace methane in the Los Angeles basin back to its sources, and found that "extra" methane is likely coming from sources related to fossil fuels.

Saharan and Asian dust, biological particles end global journey in California

Saharan and Asian dust, biological particles end global journey in California

A field study of aerosol impacts on clouds and precipitation in the Sierra Nevada mountains shows that dust and microorganisms transported from as far away as the Sahara desert help to spur the precipitation that California counts on for its water supply.
