Scientists want to solve puzzle of excess water vapor near cirrus clouds
A number of researchers in recent years have reported perplexing findings of water vapor at concentrations as much as twice what they should be in and around cirrus clouds high in the atmosphere, a finding that could alter some conclusions about climate change. view more (2006-12-01)
Missing Link to Cloud Formation Found
New chemical research shows how cloud seedlings form over forested areas. view more (2009-08-11)
Tiny airborne particles are a major cause of climate change
A scientist at the Weizmann Institute of Science and his colleagues caused a storm in the atmospheric community when they suggested a few years back that tiny airborne particles, known as aerosols, may be one of the main culprits causing climate change - having, on a local scale, an even greater impact than the greenhouse gases effect. view more (2006-07-19)
Invisible gases form most organic haze in urban, rural areas
A new study involving the University of Colorado at Boulder shows that invisible, reactive gases hovering over Earth's surface, not direct emissions of particulates, form the bulk of organic haze in both urban and rural areas around the world. view more (2007-07-10)
Seismic images show dinosaur-killing meteor made bigger splash
The most detailed three-dimensional seismic images yet of the Chicxulub crater, a mostly submerged and buried impact crater on the Mexico coast, may modify a theory explaining the extinction of 70 percent of life on Earth 65 million years ago. view more (2008-01-24)
Dirty air brings rain -- then again, maybe not
An international team of scientists, headed by Prof. Daniel Rosenfeld of the Institute of Earth Sciences at the Hebrew University of Jerusalem, has come up with a surprising finding to the disputed issue of whether air pollution increases or decreases rainfall. The conclusion: both can be true, depending on local environmental conditions. view more (2008-09-08)
Volcanoes helped slow ocean warming trend, researchers find
Ocean temperatures might have risen even higher during the last century if it weren't for volcanoes that spewed ashes and aerosols into the upper atmosphere, researchers have found. The eruptions also offset a large percentage of sea level rise caused by human activity. view more (2006-02-10)
New satellite set to collect most-detailed data yet about atmospheric particles
A new satellite that last week began gathering data from the Earth's atmosphere could be a key tool in unraveling just how much effect the reflectivity of clouds and tiny particles called aerosols are having on the planet's changing climate. view more (2006-06-13)
NASA satellite measures pollution from east Asia to North America
In a new NASA study, researchers taking advantage of improvements in satellite sensor capabilities offer the first measurement-based estimate of the amount of pollution from East Asian forest fires, urban exhaust, and industrial production that makes its way to western North America. view more (2008-03-18)
Reducing air pollution could increase rice harvests in India
New research from the University of California indicates that reductions of human-generated air pollution could create unexpected agricultural benefits in one of the world's poorest regions. These new findings will be published online the week of Dec. 4 in the journal Proceedings of the National Academy of Sciences (PNAS). view more (2006-12-05)
Tiny dust particles from Asian deserts common over western United States
It has been a decade since University of Washington scientists first pinpointed specific instances of air pollution, including Gobi Desert dust, traversing the Pacific Ocean and adding to the mix of atmospheric pollution already present along the West Coast of North America. view more (2007-12-13)
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)
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)
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)
Gassed by gannets!
This is one of the subjects being investigated in the GANE (Global Atmospheric Nitrogen Enrichment) research initiative funded by NERC. The first meeting of the principal investigators will be on Thursday, 9th March, when they will share information on progress of the various projects that form the initiative. view more (2000-03-08)
Rats on a road trip reveal pollution-heart disease risk
Rats that rode in a truck on the New York State Thruway between Rochester and Buffalo and were exposed to the same highway pollution that motorists encounter, showed a drop in heart rate and effects on the autonomic nervous system view more (2007-02-01)
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)
Scientists to Assess Beijing Olympics Air Pollution Control Efforts
As the Summer Olympics in Beijing kicks off this week, the event is giving scientists a once-in-a-lifetime opportunity to observe how the atmosphere responds when a heavily populated region substantially curbs everyday industrial emissions. view more (2008-08-11)
Researchers to Scrutinize Megacity Pollution During Mexico City Field Campaign
A team of researchers from the National Center for Atmospheric Research (NCAR) and other institutions is heading to Mexico City to participate in one of the most complex field campaigns ever undertaken in atmospheric chemistry. view more (2006-03-03)
