Interactions of bromine, chlorine, and iodine photochemistry during ozone depletions in Barrow, Alaska
The springtime depletion of tropospheric ozone in the Arctic is known to be caused by active halogen photochemistry resulting from halogen atom precursors emitted from snow, ice, or aerosol surfaces. The role of bromine in driving ozone depletion events (ODEs) has been generally accepted, but much less is known about the role of chlorine radicals in ozone depletion chemistry. While the potentia...
متن کاملA one dimensional model study of the mechanism of halogen liberation and vertical transport in the polar troposphere
Sudden depletions of tropospheric ozone during spring were reported from the Arctic and also from Antarctic coastal sites. Field studies showed that those depletion events are caused by reactive halogen species, especially bromine compounds. However the source and seasonal variation of reactive halogen species is still not completely understood. There are several indications that the halogen mo...

Custard, Kyle David. PhD., Purdue University, May 2015. Studies of Arctic Halogen Chemistry from the Snowpack to the Gas Phase. Major Professor: Paul B. Shepson. The temporary depletion of both tropospheric ozone and gaseous mercury during the Arctic springtime has been a focus of active research over the past several decades. Both of these phenomena have been linked to chemical reactions with ...
متن کاملVariation of mesospheric ozone during the highly relativistic electron event in May 1992 as measured by the High Resolution Doppler Imager instrument on UARS
Highly relativistic electron precipitation events (HREs) include long-lived enhancements of the flux of electrons with E > 1 MeV into the Earth's atmosphere. HREs also contain increased fluxes of electrons with energies above 100 keV that have been predicted to cause large depletions of mesospheric ozone. For some of the measured instantaneous values of the electron fluxes during the HRE of May...
