NASA has begun its latest hurricane science field campaign by flying an unmanned Global Hawk aircraft over Hurricane Leslie in the Atlantic Ocean during a day-long flight from California to Virginia
A NASA-sponsored expedition is set to sail to the North Atlantic's saltiest spot to see how salinity variations are related to global rainfall shifts.
Suomi NPP captured this view of Hurricane Isaac's clouds (lit by moonlight) and the cities near the Gulf Coast of the United States at 1:57 a.m. local time.
A new NASA-funded study has largely accounted for the dramatic leveling-off in atmospheric methane levels seen at the end of the 20th century.
Powerful fires currently scorching parts of Russia and Africa sent up plumes of smoke into the atmosphere, observed by Suomi NPP.
Scientists tracked space shuttle exhaust plumes to study airflow in the upper atmosphere. The water vapor spread faster than expected and collected near the Arctic to form noctilucent clouds.
The declining sea ice in the Arctic Ocean has melted down to its smallest size since satellite observations began in the late 1970s. The current size of the polar cap surpassed the previous record set in 2007.
NASA's Operation IceBridge gathers data on changing Arctic sea ice, including new data that could be used in future seasonal sea ice forecasts.
Seven years ago on Aug. 29 the center of Hurricane Katrina moved ashore near the Louisiana-Mississippi border. Read all of the storm history here.
NASA Langley's expanding climate research hub in Hampton, Va., is now part of a worldwide network of atmospheric measurements.
HS3, will study hurricanes at the end of the summer, flying two high-altitude, long-duration unmanned aircraft with different instruments over the storms.
Radar images of Colorado's centuries-old Slumgullion landslide from NASA's C-20A Earth science aircraft aid scientists' understanding of slide motion.
An unusually strong storm formed off the coast of Alaska on August 5 and tracked into the center of the Arctic Ocean.
Urban pollution, such as formaldehyde, that winds up in Earth's upper atmosphere can wreak havoc on the ozone layer.
Late on Aug. 6, 2012, New Zealand’s Mount Tongariro erupted for the first time in 115 years.
A key ingredient for 'night shining clouds' comes from outer space. Scientists have detected bits of 'meteor smoke' imbedded in them.
NASA's Hurricane and Severe Storm Sentinel, or HS3, mission will be a complex one for the pilots flying NASA's Global Hawk aircraft from the ground.
A new statistical analysis by NASA scientists has found that Earth's land areas have become much more likely to experience an extreme summer heat wave than they were in the middle of the 20th century.
Scientists used satellites to measure for the first time from space the amount of tiny airborne particles entering North America, and concluded that dust, not pollution, is the main ingredient of the imported particles.
Atmospheric scientist Hongbin Yu describes the implications of a new calculation showing that 64 million tons of dust, pollution and other particles survive a trans-ocean journey to arrive over North America each year.
