Ozone levels across much of North America and Europe dropped significantly between 2000 and 2014. People living in parts of southern Europe, South Korea and southern Japan and China also experienced more than 15 days a year of ozone levels above 70 ppb.

Satellite method provides insight into ozone-NOx-VOCs sensitivity for different locations

Green Car Congress

Ozone pollution near Earth’s surface is one of the main ingredients of summertime smog. It is also not directly measurable from space due to the abundance of ozone higher in the atmosphere, which obscures measurements of surface ozone. —Jin et al.

Researchers report on potential long-range atmospheric emissions impacts of increased ethanol fuel use in North America

Green Car Congress

Seasonal ethanol emissions from North America. Numbers inset give the total North American ethanol source. Ethanol is emitted to the atmosphere by both natural and anthropogenic processes; examples of the latter include industrial processes, biomass combustion and use as a biofuel mixed with gasoline.

EPA, NSF, NOAA, Southern Company and EPRI contribute >$20M to fund SouthEast Atmosphere Study

Green Car Congress

SOAS objectives include the direct quantification of VOC, ozone and NO x surface fluxes and the reconciliation of differences with “blank-down” emission estimates. It seeks a better understanding of HO x /NO x /ozone/organics/aerosol distributions, sources and sinks. These goals will be fully met in the merged project.
