NASA to study how pollution, storms and climate mix

(Phys.org) —NASA aircraft will take to the skies over the southern United States this summer to investigate how air pollution and natural emissions, which are pushed high into the atmosphere by large storms, affect atmospheric ...

Surprising predictor of ecosystem chemistry

Carnegie scientists have found that the plant species making up an ecosystem are better predictors of ecosystem chemistry than environmental conditions such as terrain, geology, or altitude. This is the first study using ...

NASA chases climate change clues into the stratosphere

Starting this month, NASA will send a remotely piloted research aircraft as high as 65,000 feet over the tropical Pacific Ocean to probe unexplored regions of the upper atmosphere for answers to how a warming climate is changing ...

What dust may have to do with Earth's rapidly warming poles

(Phys.org)—As earth's climate warms, scientists have tried to understand why the poles are heating up two to three times faster than the rest of the planet. Airborne dust, it turns out, may play a key role.

SOFIA to embark on new cycle of science observations

(Phys.org)—The Stratospheric Observatory for Infrared Astronomy, or SOFIA, a joint program between NASA and the German Aerospace Center DLR, is set to begin its first full cycle of science flights starting in November 2012 ...

NASA's IceBridge seeking new view of changing sea ice

This year scientists working on NASA's Operation IceBridge, a multi-year airborne science mission to study changing ice conditions at both poles, debuted a new data product with the potential to improve Arctic sea ice forecasts.

NASA selects science instrument upgrade for flying observatory

NASA has selected a science instrument upgrade to the Stratospheric Observatory for Infrared Astronomy (SOFIA) airborne observatory. The instrument, the High-resolution Airborne Wideband Camera (HAWC), will provide a sensitive, ...
