NASA to launch newest Earth-observation satellite

(AP) -- NASA is set to launch its latest Earth-orbiting satellite on a $424 million mission to analyze airborne grit spewed by volcanoes, forest fires, smokestacks and tailpipes.

Glory promises new view of perplexing particles

Climatologists have known for decades that airborne particles called aerosols can have a powerful impact on the climate. However, pinpointing the magnitude of the effect has proven challenging because of difficulties associated ...

Aerosols: From Ash in the Wind to Smoke from the Stack

(PhysOrg.com) -- When we hear the word "aerosol," most of us think of spray cans and perhaps the ozone hole. But spray cans are just a very small part of the story. Any airborne solid particle or liquid droplet -- whether ...

Satellite data improve aviation safety

(PhysOrg.com) -- Thousands of planes are grounded across Europe due to the spread of volcanic ash following the recent eruption under Iceland's Eyjafjallajoekull glacier. Volcanic eruptions eject large amounts of ash and ...

Image: Measuring clouds and aerosols from the space station

Clouds can be observed from the International Space Station moving across Earth's surface, as in this image of New Zealand taken by Expedition 42 Flight Engineer Samantha Cristoforetti. Other tiny solid and liquid particles ...

Models without volcanic forcing underestimate sea level rise

Volcanic eruptions spew sulfur dioxide into the atmosphere, which tends to block incoming sunlight, sometimes cooling the planet for several years. This cooling leads to a decrease in the heat stored in the ocean and thus ...
