High-altitude aircraft data may help improve climate models
Sulfur dioxide released from volcanoes or power plants causes acid rain and leads to particles that play a role in breaking down the protective ozone layer high in the atmosphere. But those particles also reflect sunlight away from Earth, leading some to propose that people could inject sulfur dioxide (SO2) high in the atmosphere to mitigate global warming. New research in Geophysical Research Letters provides the first actual measurements of the chemical, SO2, in the tropical upper troposphere/lower stratosphere—and there’s a whole lot less than some scientists estimated.
“These new data will be important for improving climate models, evaluating satellite data, and understanding the potential of climate intervention scenarios,” said lead author Andrew Rollins, a scientist with the Cooperative Institute for Research in Environmental Sciences (CIRES) at the University of Colorado Boulder who works in the NOAA Earth System Research Laboratory (ESRL)…more

Featured Special Collection
Early results from Juno's mission at Jupiter including approach to Jupiter and the first perijove pass (PJ1). Juno's scientific objectives include the study of Jupiter's interior, atmosphere and polar magnetosphere with the goal of understanding Jupiter's origin, formation and evolution. This collection of papers provides early results from Juno's measurements of the gravity and magnetic fields, deep atmospheric microwave sounding, infrared, visible and ultraviolet images/spectra and an array of fields and particles instruments as well as context for the early results with respect to current theory and models of Jupiter's formation and evolution. Topics include both Juno - Jupiter related theoretical models and data analysis as well as collaborative observations made from Earth based assets.
