Study Says Lightning Produces an 'Atmospheric Detergent'

0 comments
As people grow more and more comfortable performing scientific experiments in the sky, we continue to learn more about ever-mysterious lightning. A new study in the journal
Science provides the latest insight into the illusive electrostatic discharges; outlining evidence supporting the idea that they are indeed a “detergent of the atmosphere.”
The Smithsonian Magazine reported on the new study, which researchers at Penn State authored. William H. Brune, a professor of meteorology at the university, led the researchers as they looked back on data a NASA jet measured in storm clouds over Colorado, Oklahoma, and Texas in 2012.
During its June 2012 run, NASA’s jet specifically measured two molecules in the storm clouds: hydroxyl radicals (OH) and hydroperoxyl radicals (OH2). Scientists refer to the former molecule as an atmospheric “detergent” because it reacts with, and decomposes, pollutants. Hydroxyl also plays a key role in removing greenhous ....

Lightning and subvisible discharges produce molecules that clean the atmosphere -- Science & Technology -- Sott.net

Nitrogen, oxygen and water vapor molecules are broken apart by lightning and associated weaker electrical discharges, generating the reactive gases NO, O3, HO2, and the atmosphere s cleanser, OH.
Lightning bolts break apart nitrogen and oxygen molecules in the atmosphere and create reactive chemicals that affect greenhouse gases. Now, a team of atmospheric chemists and lightning scientists have found that
lightning bolts and, surprisingly, subvisible discharges that cannot be seen by cameras or the naked eye produce extreme amounts of the hydroxyl radical OH and hydroperoxyl radical HO
2.
The hydroxyl radical is important in the atmosphere because it initiates chemical reactions and breaks down molecules like the greenhouse gas methane. OH is the main driver of many compositional changes in the atmosphere. ....
