Satellite observations have revealed the first direct evidence of smoke from Arctic wildfires drifting over the Greenland ice sheet, tarnishing the ice with soot and making it more likely to melt under the sun.
Over the next few weeks, an ER-2 high altitude research aircraft operating out of NASA's Wallops Flight Facility in Wallops Island, Va., will take part in the development of two future satellite instruments. The aircraft ...
(Phys.org) -- NASA and university scientists have made the first measurement-based estimate of the amount and composition of tiny airborne particles that arrive in the air over North America each year. With a 3-D view of ...
Dust and aerosol pollution from Asia travels across the ocean and sullies the air in the United States and Canada, possibly worsening the effects of climate change, a study showed Thursday.
(Phys.org) -- High above the Earth, clouds too thin to see cover the tropics. Scientists at Pacific Northwest National Laboratory have found a creative technique to identify the clouds' origins. Using several satellite data ...
(PhysOrg.com) -- It's no surprise that humans the world over use more water, by volume, than any other material. But in second place, at over 17 billion tons consumed each year, comes concrete made with Portland cement. Portland ...
(PhysOrg.com) -- A NASA-led study has documented an unprecedented depletion of Earth's protective ozone layer above the Arctic last winter and spring caused by an unusually prolonged period of extremely low temperatures in ...
(PhysOrg.com) -- A new study led by the U.S, National Oceanic and Atmospheric Administration (NOAA) shows that tiny particles that make their way all the way up into the stratosphere may be offsetting a global rise in temperatures ...
Scientists, photographers and amateur cloud watchers have been looking up with wonderment and puzzlement at "hole punch" clouds for decades. Giant, open spaces appear in otherwise continuous cloud cover, presenting beautiful ...
Researchers have found that areas near commercial airports sometimes experience a small but measurable increase in rain and snow when aircraft take off and land under certain atmospheric conditions.
