Atmospheric chemists are puzzled, says Jacob, by the mechanism which controls the concentration of ozone in the troposphere, and he finds this embarrassing...
With an eye for answering these and other questions, McKay Associate Professor of Atmospheric Chemistry Daniel J. Jacob has developed a model which he says explains the sudden loss of tropospheric ozone over the Arctic each spring, and possibly over one area of the equatorial Pacific...
...most noble quests in atmospheric chemistry today," Jacob says. "It's kind of the Holy Grail, to try to understand what controls tropospheric ozone, because then you will understand a lot of other things...
...model proposed by Jacob and Research Assistant Song-Miao Fan explains how unreactive bromine combines with acid particles present in human pollution and is then activated by light so it can "eat" more ozone...
Using Arctic ozone data, Jacob was able to prove that a reaction catalyzed by bromine was involved in the destruction of tropospheric ozone...
