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 »Atmospheric Sciences
New research provides a comprehensive overview of the effect of the Asian summer monsoon (ASM) on atmospheric composition throughout the life cycle of the ASM anticyclone.Read More »Atmospheric Sciences
A simplified view of ozone chemistry can cause climate models to overestimate the response of jet streams to increasing greenhouse gases.Read More »Atmospheric Sciences
Enhanced technology and chemistry-climate models have advanced our understanding of the sources and processes controlling the evolution of the stratospheric aerosol layer, the so-called Junge layer.Read More »
