Intense boreal forest fires in August 2017 caused smoke plumes that reached record levels in the stratosphere; satellite measurements show that the effects rivaled a moderate volcanic eruption.Read More »Atmospheric Sciences
With the space industry’s rapid growth, rocket exhaust will increasingly accumulate in the atmosphere. How this accumulation might affect the planet is unknown—because we’re not taking it seriously.Read More »
Since the 1970s, the stratosphere has cooled as ozone levels dropped and carbon dioxide levels increased. Chemical models of the temperature decline conflicted with satellite observations—until now.Read More »Atmospheric Sciences
For the first time, simultaneous measurements of upper atmosphere temperatures over altitudes 80 to 110 kilometers have been made by two complementary lidar techniques.Read More »Atmospheric Sciences
High above Earth’s surface, air temperatures occasionally increase suddenly, producing widespread effects on weather, air chemistry, and telecommunications.Read More »Atmospheric Sciences
By harnessing satellite data collected from low-Earth orbit, scientists can now track the distribution of atmospheric nitrous oxide and its isotopes.Read More »
Measurements show that a decline in chlorine due to the Montreal Protocol has resulted in about 20 percent less ozone depletion during the Antarctic winter than there was in 2005.Read More »
