Latest A-train Stories
Mention the "A-Train" and most people probably think of the jazz legend Billy Strayhorn or perhaps New York City subway trains â€” not climate change.
Using data from several research satellites, scientists will spend the next three years trying to understand the climate impacts of about 770 million tons of dust carried into the atmosphere every year from the Sahara Desert.
After nearly 5 years of concurrent operations with the Afternoon Constellation, known as the "A-Train," the PARASOL satellite is going on another orbit "track."
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 often contentious debate about global warming has been absent a critical component: an accurate measurement of precisely how much carbon dioxide (CO2) is in the air, and how it is being recycled by the planet.
Clouds have typically posed a problem to scientists using satellites to observe the lowest part of the atmosphere, where humans live and breathe.
New findings from NASA's CloudSat and other spacecraft in NASA's "A-Train" constellation of five Earth observing satellites offer important insights into this year's record reduction of Arctic sea ice, global rainfall patterns and the effects of pollution on clouds.
The first images from NASA's new CloudSat satellite are already revealing never-before-seen 3-D details about clouds.
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.
