Detection of missing sulfur dioxide sources

Detection of missing sulfur dioxide sources

A new emission-source detection algorithm was applied to the measurements of sulfur dioxide from the Ozone Monitoring Instrument. It was used to compile the first global, satellite-based emissions inventory, and is completely independent of conventional information sources.

Low ozone over Europe doesn't mean the sky is falling, it's actually rising

To quantitatively understand anthropogenic impacts to the stratospheric ozone layer, we must be able to distinguish between low ozone caused by ozone depleting substances and that caused by natural dynamical variability in the atmosphere.
