Latest CALIPSO Stories
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."

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.
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.
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.
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.
Clouds have typically posed a problem to scientists using satellites to observe the lowest part of the atmosphere, where humans live and breathe.
Far beyond signaling the dayâ€™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.
NASA on Friday launched two research satellites to help scientists refine computer models that forecast the weather and chart global climate change.
