The air we breathe doesn't always come from our own backyard. In fact, sometimes it doesn't even come from our neighbors. On April 22, 2010, a NASA satellite captured the appearance of a large dust cloud over the eastern coast of United States that originated on the other side of the world -- in China. "Dust can stimulate the production of more clouds, altering local weather and potentially the climate," said Zhoayan Liu, a researcher at the National Institute of Aerospace and NASA's Langley...

NSF-supported climate scientist Mark Flanner and colleagues find differences in the rates for spring warming and snow cover decline in Eurasia and North America, and are studying whether aerosols are a key factor Over the past 30 years, springtime snow melt and warming appear to be proceeding at a faster rate in Eurasia than in North America. Climate scientist Mark Flanner, an assistant professor at the University of Michigan and a recent Advanced Study Program graduate at the National...

Workers and residents exposed to dust and fumes caused by the collapse of the World Trade Center on September 11, 2001 frequently reported headache years later, according to research released today that will be presented at the American Academy of Neurology's 62nd Annual Meeting in Toronto April 10 to April 17, 2010. "We knew that headaches were common in people living and working near the World Trade Center on and immediately after 9/11, but this is the first study to look at headaches...

A Japanese study using a NASA satellite found that dust clouds being generated by a huge dust storm in China's Taklimakan desert in 2007 made more than one full circle around the globe in just 13 days. Once the cloud reached the Pacific Ocean the second time, it descended down and deposited some of its dust into the sea, revealing how a natural phenomenon can impact the environment far away. "Asian dust is usually deposited near the Yellow Sea, around the Japan area, while Sahara dust ends...

In the context of the climatic change of the planet, those research works that throw light on global warming are of great interest. That is the case of the studies on atmospheric aerosol, a suspension of solid or liquid particles on a gaseous environment that can contribute to the warming or cooling of the atmosphere. Juan Luis Guerrero Rascado developed his doctoral thesis "Lidar Technique for atmospheric characterization by elastic and Raman dispersion" precisely in this research line,...

Scientists of the Soil Science and Geopharmacy Research Group of the University of Granada (Spain), directed by Rafael Delgado, have discovered and characterized a new type of atmospheric aerosols named 'iberulites', which could be useful for the study of relevant atmospheric reactions from Earth. Researchers Jos© Luis Díaz Hernández, of the Andalusian Research and Farming, Fishing, Food, and Ecological Production Training Institute (IFAPA) and...

By Phillips, Vaughan T J DeMott, Paul J; Andronache, Constantin ABSTRACT A novel, flexible framework is proposed for parameterizing the heterogeneous nucleation of ice within clouds. It has empirically derived dependencies on the chemistry and surface area of multiple species of ice nucleus (IN) aerosols. Effects from variability in mean size, spectral width, and mass loading of aerosols are represented via their influences on surface area. The parameterization is intended for application...

By Docksai, Rick A layer of dust won't complement your bookshelf, but its presence may be a sign of good news about future hurricanes. The 2008 hurricane season was milder due to the increased presence of dust clouds over the Atlantic Ocean, according to Amato Evan, a researcher for the University of Wisconsin-Madison's Cooperative Institute for Meteorological Satellite Studies. "If those dust storms continue to intensify, that would certainly help to quell this period of intense hurricane...
