Study finds pollution emitted near equator has biggest impact on global ozone

Green Car Congress

Higher temperatures near the equator also increase the vertical motion of air, transporting ozone-forming chemicals higher in the troposphere, where they can live longer and form more ozone. Jason West (2016) “Tropospheric ozone change from 1980 to 2010 dominated by equatorward redistribution of emissions”. —Owen R.

Discovery of mechanism for atmospheric particle formation suggests need for ammonia emission regulations

Green Car Congress

The presence of ammonia was first discovered in the upper troposphere in 2016 using the analysis of averaged MIPAS (Michelson Interferometer for Passive Atmospheric Sounding) infrared limb-emission spectra. Ammonia is primarily derived from agriculture and vehicles in condensed city settings. Additionally, co-author Brandon Lopez, a Ph.D.
