Laboratory chamber walls have been stealing vapors, causing researchers to underestimate the formation of secondary organic aerosol in the atmosphere. A study published April 7 in PNAS Online Early Edition describes how a team of scientists, including researchers from the University of California, Davis, showed that vapor losses to the walls of laboratory chambers can suppress the formation of secondary organic aerosol, which in turn has contributed to the underprediction of SOA in climate...

Sunset Colors In Famous Paintings Used To Estimate Past Pollution Levels
2014-03-26 07:06:50

redOrbit Staff & Wire Reports - Your Universe Online The colors used by legendary artists of the past to depict a sunset could be used to estimate pollution levels in the atmosphere during bygone days, according to research published Tuesday in the open-access journal Atmospheric Chemistry and Physics. Lead author Christos Zerefos, a professor of atmospheric physics at the Academy of Athens in Greece, and his colleagues showed that paintings of famous artists reveal the ash and gas...

Dust Kicked Up In Asia Strengthens Monsoons In India
2014-03-17 10:18:29

Mary Beckman, DOE/Pacific Northwest National Laboratory A new analysis of satellite data reveals a link between dust in North Africa and West Asia and stronger monsoons in India. The study shows that dust in the air absorbs sunlight west of India, warming the air and strengthening the winds carrying moisture eastward. This results in more monsoon rainfall about a week later in India. The results explain one way that dust can affect the climate, filling in previously unknown details about...

long term warming trend

WASHINGTON, March 11, 2014 /PRNewswire-USNewswire/ -- A new NASA study shows Earth's climate likely will continue to warm during this century on track with previous estimates, despite the recent slowdown in the rate of global warming. This research hinges on a new and more detailed calculation of the sensitivity of Earth's climate to the factors that cause it to change, such as greenhouse gas emissions. Drew Shindell, a climatologist at NASA's Goddard Institute for Space Studies in New...

Nature: Researchers discover source of climate-active organic aerosol particles According to their results, these extremely low-volatile organic compounds consist of relatively large molecules which contain an almost equal number of carbon, oxygen, and hydrogen atoms. The scientists present a plausible explanation supported by numerous experimental findings of how these vapours are formed almost immediately when plant emissions (e.g. monoterpenes) are released into the air. The vapours can...

when a pine-scented molecule combines with ozone in the surrounding air, some of the free radicals created in the process grab oxygen with unprecedented speed
2014-02-27 06:28:35

April Flowers for redOrbit.com - Your Universe Online For atmospheric scientists, pine forests are magical places where coniferous trees give off pine-scented vapors. These vapors form particles, rapidly and seemingly out of nowhere. A new study from an international group of scientists illuminates the process by which gas wafting from coniferous trees creates particles that can reflect sunlight or promote cloud formation. Both are important climate feedbacks. The findings, led by the...

Ancient Earth Was Warmer Due To Forest Emissions And Wildfires

[ Watch the Video: Wildfires Heated Up The Early Earth ] Lee Rannals for redOrbit.com - Your Universe Online According to a new study published in the journal Geophysical Research Letters, wildfires could explain why the Earth was so hot three million years ago. Researchers at Yale University found that volatile compounds released by ancient Earth’s forests and smoke from wildfires caused more global warming than atmospheric levels of carbon dioxide. This study provides evidence...

Air pollution in China has exhibited noticeable changes over the past 30 years, shifting from point-source pollution (around factories and industrial plants) in the 1980s to urban pollution in the 1990s. Since the start of this century, air pollution has become increasingly regional and more complex. Recent research has indicated that the cooperative transition of SO2 and NOx into secondary aerosols (sulfate and nitrate) played a critical role in the haze pollution episode in China in January...

Say researchers from the Hebrew University, US and Australia The warming effect of human-induced greenhouse gases is a given, but to what extent can we predict its future influence? That is an issue on which science is making progress, but the answers are still far from exact, say researchers from the Hebrew University of Jerusalem, the US and Australia who have studied the issue and whose work which has just appeared in the journal Science. Indeed, one could say that the picture is a...

Arctic haze is a phenomenon that occurs in the atmosphere at high latitudes in the Arctic due to air pollution. What distinguishes Arctic haze from haze found elsewhere, is the ability of its chemical ingredients to endure in the atmosphere for a longer period of time compared to other pollutants. Due to limited snowfall, rain, or turbulent air to displace pollutants from the polar air in the spring, Arctic haze can continue for more than a month in the northern atmosphere. Arctic haze was...

Haze is a type of atmospheric phenomenon where dust, smoke and dry particles in the air obscure the sky's clarity. Haze is created through various activities including farming, traffic pollution,and even wildfires. The World Meteorological Organization (WMO) categorizes the obscuration of the Earth's atmosphere by a list of different types of atmospheric phenomena. One of these is haze. The other classifications are: fog, ice fog, steam fog, mist, smoke, volcanic ash, dust, sand, and snow....
