In May 2010, the ash cloud from the Icelandic volcano Eyjafjallajökull reached the Iberian Peninsula and brought airports to a halt all over Europe. At the time, scientists followed its paths using satellites, laser detectors, sun photometers and other instruments. Two years later they have now presented the results and models that will help to prevent the consequences of such natural phenomena. The eruption of the Eyjafjallajökull in the south of Iceland began on...

Last week, teachers from the United States, Mexico, Cameroon and French Guyana joined with teachers in Puerto Rico to learn how they can take environmental studies into their own hands and back into their classrooms. At a workshop hosted by Hampton University in Hampton, Va., NASA and the Puerto Rico NASA Space Grant Consortium, participants were given the tools they need to study particles in the air in their own neighborhoods so that they can analyze how those particles, also known as...

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.From his office at NASA's Goddard Space Flight Center in Greenbelt, Md., Holben helps manage the world's largest network of ground-based sensors for aerosols -- tiny specks of solids and liquids that waft about in the atmosphere. These particles come from both human and...

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,...

By Bellantone, V Carofalo, I; De Tomasi, F; Perrone, M R; Santese, M; Tafuro, A M; Turnone, A ABSTRACT Ground-based particulate matter (PM) samplers, an XeF Raman lidar operating in the framework of the European Aerosol Research Lidar Network (EARLINET), and a sun/sky radiometer operating in the framework of the Aerosol Robotic Network (AERONET) have been used to characterize vertical profiles, optical and microphysical properties, and chemical composition of aerosols during the 29 June-1...

There seems to be something new under the sun -- in the sky, specifically -- that could complicate scientists' efforts to get a fix on how much the world will warm in the future. Greenhouse gases are not the only things in the air that influence the temperature of our atmosphere. Clouds and small airborne particles called aerosols also play an important and complicated role. And now a new ingredient has been discovered: an extensive and previously unseen "twilight zone" of particles that...
