||A Deep Ozone Hole in Spite of Low Chlorine: How Transport Affects Chemistry |
MLS ClO in the 2011 Antarctic vortex was 20% lower than 2006, yet the 2011 ozone hole is very similar to the 2006 hole, the largest ever observed.
||Homogenizing Global Sulfur Dioxide Measurements from Multiple Satellite Sensors |
Satellite mapping of sulfur dioxide (SO2) is useful to track volcanic and anthropogenic emissions in places where detailed SO2 emission information is not available.
||TES measurements demonstrate ammonia emissions are under-reported |
Ammonia (NH3) pungently affects air quality. It is also involved in the formation of aerosol PM2.5 particles, which have adverse health effects, and impacts soil acidification, biodiversity, and the nitrogen cycle.
