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)
Marine Algae A Weapon Against Global Warming?
"Parforce" an EU-funded research project has discovered a new link between marine algae and climate change. Researchers working on the project found out that iodine vapours, released from algae or plankton, condense over oceans to form aerosols . These aerosols, which tend to counter "global warming", can have a significant impact on... view more... (2002-07-18)
Science paper examines role of aerosols in climate change
A group of scientists affiliated with the International Geosphere-Biosphere Programme (IGBP) have proposed a new framework to account more accurately for the effects of aerosols on precipitation in climate models. view more (2008-09-08)
NASA study improves ability to predict aerosols' effect on cloud cover
Using a novel theoretical approach, researchers from NASA and other institutions have identified the common thread that determines how aerosols from human activity, like the particles from burning of vegetation and forests, influence cloud cover and ultimately affect climate. view more (2008-08-15)
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)
Electric sand findings could lead to better climate models
Wind isn't acting alone in the geological process behind erosion, sand dunes and airborne dust particles called aerosols. view more (2008-01-08)
Record air pollution above the Arctic
Last week Scientists of the Alfred Wegener Institute for Polar and Marine Research observed the highest air pollution on record since measurements began in Ny-Ã-lesund on Svalbard. Monitoring instruments displayed significantly increased aerosol concentrations compared to those generally found. view more (2006-05-11)
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)
Laboratory scientists study soot in megacity pollution
A team of Los Alamos scientists recently returned from a month-long data-gathering trip to Mexico City as part of an international, multi-agency environmental science collaboration. view more (2006-05-09)
Detecting secondary aerosols
EUREKA project E! 2507 EUROENVIRON COPAP has developed a new detection device that will aid research into global climate change, environmental studies, life-science research and environmental monitoring and improve understanding on aerosols. view more (2005-02-03)
Central American fires impact US air quality and climate
Scientists using NASA satellites and computer models have shown that pollutants from Central American biomass burning can influence air quality and climate in the United States. view more (2006-10-11)
Airborne dust causes ripple effect on climate far away
When a small pebble drops into a serene pool of water, it causes a ripple in the water in every direction, even disturbing distant still waters. view more (2007-01-30)
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)
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)
Seeing clearly despite the clouds
Satellites taking atmospheric measurements might now be able to see blue skies as clearly as optimists do. Researchers have found a way to reduce cloud-induced glare when satellites measure blue skies on cloudy days, by as much as ten-fold in some cases. view more (2008-05-21)
Global 'sunscreen' has likely thinned, report NASA scientists
A new NASA study has found that an important counter-balance to the warming of our planet by greenhouse gases - sunlight blocked by dust, pollution and other aerosol particles - appears to have lost ground. view more (2007-03-19)
NASA probes the sources of the world's tiny pollutants
Pinpointing pollutant sources is an important part of the ongoing battle to improve air quality and to understand its impact on climate. Scientists using NASA data recently tracked the path and distribution of aerosols — tiny particles suspended in the air — to link their region of origin and source type with their tendencies to warm... view more...

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)
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)
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)
