A NASA study finds that perennial sea ice in the Arctic is melting faster than previously thought—at a rate of 9 percent per decade.

The month of December will see the launch of three NASA research missions to help us better understand and protect our home planet while continuing to search for life in our universe and inspire the next generation of explorers.

Less precipitation and more lightning eventually may be forecast as a result of a NASA study that shows that cloud droplets freeze from the outside inward instead of the opposite.

NASA research scientist Dr. Joanne Simpson has been awarded the prestigious International Meteorological Organization Prize by the Executive Council of the World Meteorological Organization (WMO), the first woman ever to win this prize.

NASA experts in Earth and Space Science will brief reporters about two upcoming launches at noon, Tuesday, Nov. 26 in the NASA Headquarters auditorium in Washington.

NASA scientists at Stennis Space Center are using satellite data to gather information about the pollution content of Mississippi streams in order to assess threats to the local population.

In October, the Upper Atmosphere Research Satellite (UARS) completed the first measurement of the solar ultraviolet radiation spectrum over the duration of an 11 year solar cycle, a period marked by cyclical shifts in the Sun’s activity. This long measurement record by two instruments aboard UARS will give researchers better insight into how fluctuations in the Sun’s energy affect ozone and the Earth’s climate. In turn, the data set gives scientists tools to document the influence of man-made chemicals on ozone loss.

Russian researchers are studying images taken by the crew of the International Space Station to better understand the catastrophic glacier collapse and landslide that occurred on the northern slope of Mount Kazbek in September — information that may help us better understand our home

A new lightning index that uses measurements of water vapor in the atmosphere from Global Positioning Systems has improved lead-time for predicting the first lightning strikes from thunderstorms. The index will help greatly aid NASA Space Shuttle launches at Kennedy Space Center, Fla, and other commercial and US Department of Defense launches from Cape Canaveral Air Force Station, Fla.

Warmer or colder sea surface temperatures (SST) may affect one of the world’s key large-scale atmospheric circulations that regulate the intensity and breaking of rainfall associated with the South Asian and Australian monsoons, according to new research from NASA.

NASA researchers will join more than 350 scientists from the United States, the European Union, Canada, Iceland, Japan, Norway, Poland, Russia and Switzerland this winter to measure ozone and other atmospheric gases using aircraft, large and small balloons, ground-based instruments and satellites.

NASA scientists using satellite data have shown that shifts in rainfall patterns from one of the strongest El Niño events of the century in 1997 to a La Niña event in 2000 significantly changed vegetation patterns over Africa.
