The U.S. space agency said it is funding development of a satellite data system to provide aircraft pilots with updates about severe ocean storms. Scientists at the National Center for Atmospheric Research in Boulder, Colo., and at the University of Wisconsin are developing a prototype system that combines satellite data and computer weather models with cutting-edge artificial intelligence techniques. The goal is to help guide pilots away from intense storms. Turbulence is the leading cause...

Twenty years ago, Brent Holben was part of a NASA team studying vegetation from space. In an unlikely career twist, his research morphed into the study of a critical, if overlooked, subplot in the story of climate change.From his office at NASA's Goddard Space Flight Center in Greenbelt, Md., Holben helps manage the world's largest network of ground-based sensors for aerosols -- tiny specks of solids and liquids that waft about in the atmosphere. These particles come from both human and...

In the context of the climatic change of the planet, those research works that throw light on global warming are of great interest. That is the case of the studies on atmospheric aerosol, a suspension of solid or liquid particles on a gaseous environment that can contribute to the warming or cooling of the atmosphere. Juan Luis Guerrero Rascado developed his doctoral thesis "Lidar Technique for atmospheric characterization by elastic and Raman dispersion" precisely in this research line,...

HAMPTON, Va., April 16 /PRNewswire-USNewswire/ -- A space-borne lidar mission developed by NASA and the French space agency Centre National d'Etudes Spatiales (CNES) has successfully made the switch from its first laser to its back-up, guaranteeing a continued stream of data that is allowing scientists to better understand the complex roles clouds and aerosols play in Earth's climate. The extended data set will help capture the pattern of year-to-year variations in cloudiness and the...

As the summer fire season heats up, NASA aircraft are set to follow the trail of smoke plumes from some of Earth's northernmost forest fires, examining their contribution to arctic pollution and implications for climate change.Starting June 29, NASA's DC-8 and P-3B aircraft, based at a Canadian military base in Cold Lake, Alberta, will begin their final three-week deployment of the Arctic Research of the Composition of the Troposphere from Aircraft and Satellites, or ARCTAS, mission. A third...

Clouds have typically posed a problem to scientists using satellites to observe the lowest part of the atmosphere, where humans live and breathe, because they block the satellite's ability to capture a clear, unobstructed view of Earth's surface. It turns out, however, that these "obstructions" are worth a closer look, as clouds and their characteristics actually serve a valuable role in Earth's climate. That closer look is now available by satellites comprising the Afternoon Constellation,...

Far beyond signaling the day's weather, clouds play a key role in regulating and understanding climate. A team of researchers recently completed a project to confirm what NASA satellites are telling us about how changes in clouds can affect climate in the coldest regions on Earth. Clouds and their traits "“ their temperature, depth, size and shape of their droplets "“ play a significant role in how much of the sun's radiation reaches Earth's surface and what amount of heat energy...

By Irene Klotz CAPE CANAVERAL, Florida -- NASA on Friday launched two research satellites to help scientists refine computer models that forecast the weather and chart global climate change. CloudSat and CALIPSO blasted off aboard an unmanned Delta rocket from Vandenberg Air Force Base in California at 6:02 a.m. EDT (1002 GMT) after a week of delays for weather and technical issues. The Boeing-built booster originally had been slated to fly last year, but a machinists' strike forced several...

JPL -- Two NASA satellites, planned for launch no earlier than Oct. 26, will give us a unique view of Earth's atmosphere. CloudSat and Cloud-Aerosol Lidar and Infrared Pathfinder Satellite Observations (Calipso) are undergoing final preparations for launch from Vandenberg Air Force Base, Calif. CloudSat and Calipso will provide a new, 3-D perspective on Earth's clouds and airborne particles called aerosols. The satellites will answer questions about how clouds and aerosols form, evolve and...
