Although most people might think smoke rises and then clears after a fire has been extinguished, the opposite is actually true. New research using data collected during NASA airborne science campaigns shows how smoke from wildfires worldwide could impact the atmosphere and climate much more than previously thought. The study, led by researchers at the

On Nov. 7, 2018, NASA’s Operation IceBridge flew over an iceberg three times the size of Manhattan—the first time anyone has laid eyes on the giant iceberg, dubbed B-46 by the U.S. National Ice Center, that broke off from Pine Island Glacier in late October. As NASA’s DC-8 flew its predetermined flight pattern, the new

The ozone hole that forms over the Antarctic each September is primarily driven by two factors: the amount of ozone-destroying chlorine in the polar stratosphere and the availability of ice crystals in stratospheric clouds for the chlorine to bind to. This year, the super-cold stratospheric temperatures measured by NOAA and NASA meant conditions were ripe

The Florida Keys coral reefs stopped growing or significantly slowed their growth at least 3,000 years ago and have been balanced between persistence and erosion ever since, according to a new study by the U.S. Geological Survey (USGS). The study, published in the journal Global Change Biology, also points to coral bleaching and disease outbreaks

CloudSat and CALIPSO, designed to complement each other in the 1990s, were launched together on the same rocket in 2006. Then they spent more than 10 years orbiting Earth in formation with a coterie of other satellites in what’s known as the A-Train (afternoon constellation). Flying together enables the A Train satellites to gather diverse
