Climate studies to benefit from 12 years of satellite aerosol data
Aerosols, very small particles suspended in the air, play an important role in the global climate balance and in regulating climate change. view more (2009-11-11)
Interactions with aerosols boost warming potential of some gases
For decades, climate scientists have worked to identify and measure key substances -- notably greenhouse gases and aerosol particles -- that affect Earth's climate. view more (2009-10-30)
Do dust particles curb climate change?
A knowledge gap exists in the area of climate research: for decades, scientists have been asking themselves whether, and to what extent man-made aerosols, that is, dust particles suspended in the atmosphere, enlarge the cloud cover and thus curb climate warming. view more (2009-10-07)
Water in a changing climate
New research announced at the international Water in a changing climate science conference in Melbourne 24-28 August, implicates pollution from Asia, Europe and North America as a contributor to recent Australian rainfall changes. view more (2009-08-27)
The greenhouse gas that saved the world
When Planet Earth was just cooling down from its fiery creation, the sun was faint and young. So faint that it should not have been able to keep the oceans of earth from freezing. But fortunately for the creation of life, water was kept liquid on our young planet. view more (2009-08-18)
The Sky Is Not Falling: Pollution in eastern China cuts light, useful rainfall
New research shows that air pollution in eastern China has reduced the amount of light rainfall over the past 50 years and decreased by 23 percent the number of days of light rain in the eastern half of the country. view more (2009-08-17)

World's largest aerosol sensing network has leafy origins
Twenty years ago, Brent Holben was part of a NASA team studying vegetation from space. In an unlikely career twist, his research morphed into the study of a critical, if overlooked, subplot in the story of climate change. view more (2009-06-30)
Hand-held aerosol sensors help fill crucial data gap over oceans
Since NASA researchers began assembling the Aerosol Robotic Network (AERONET) in the 1990s, the worldwide network of ground-based aerosol sensors has grown to 400 sites across seven continents. view more (2009-06-30)
Sulfate lens enhances climate warming properties of atmospheric soot
Particulate pollution thought to be holding climate change in check by reflecting sunlight instead enhances warming when combined with airborne soot, a new study has found. view more (2009-06-30)
Salt block unexpectedly stretches in Sandia experiments
To stretch a supply of salt generally means using it sparingly. view more (2009-06-24)
UCSD researchers make first direct observations of biological particles in high-altitude ice clouds
A team of UC San Diego-led atmospheric chemistry researchers moved closer to what is considered the "holy grail" of climate change science when it made the first-ever direct detection of biological particles within ice clouds. view more (2009-05-18)
Aerosols may drive a significant portion of arctic warming
Though greenhouse gases are invariably at the center of discussions about global climate change, new NASA research suggests that much of the atmospheric warming observed in the Arctic since 1976 may be due to changes in tiny airborne particles called aerosols. view more (2009-04-09)
New aerosol observing technique turns gray skies to blue
Tiny, ubiquitous particles in the atmosphere may play a profound role in regulating global climate. But the scientists who study these particles -- called aerosols -- have long struggled to accurately measure their composition, size, and global distribution. view more (2009-03-13)
Study calls for increased research in flu transmission to prepare for pandemic flu outbreak
Researchers at Rhode Island Hospital have completed a study to better understand the impact of infection control measures during a possible flu pandemic. view more (2009-02-19)
Aerosols - their part in our rainfall
Aerosols may have a greater impact on patterns of Australian rainfall and future climate change than previously thought, according to leading atmospheric scientist, CSIRO's Dr Leon Rotstayn. view more (2009-02-12)
LSU Engineers model forecasts chemical contaminants based on Katrina-flooded homes
A recent study by LSU engineers suggests that Katrina-flooded homes may contain harmful levels of contaminants, particularly aerosols and gases, which could expose first-responders, residents and any others entering such homes to serious and lasting health risks. The results could also be applied to similar flooding events that might occur in the... view more... (2009-02-05)
Newly described contaminant sources in Katrina-flooded homes pose health risks
Post-Katrina flooded homes may contain harmful levels of contaminants in addition to sediment deposits. Indoor gases, mold films, and aerosols may also have exposed residents, first responders, and demolition crews to dangerous contaminant levels without the need for direct skin contact. view more (2009-02-03)
Report calls aerosol research key to improving climate predictions
Scientists need a more detailed understanding of how human-produced atmospheric particles, called aerosols, affect climate in order to produce better predictions of Earth's future climate, according to a NASA-led report issued by the U.S. Climate Change Science Program on Friday. view more (2009-01-20)
VAMOS Ocean Cloud Atmosphere Land Study
The clouds being investigated in this study are known as marine stratocumulus clouds. They tend to form adjacent to continents where deep, cold, upwelling water reaches the sea-surface. view more (2008-10-22)
