Halogen emissions from a small volcanic eruption: modeling the peak concentrations, dispersion, and volcanically induced ozone loss in the stratosphere

Abstract:

Aircraft measurements in the Hekla, Iceland volcanic plume in February 2000 revealed large quantities of hydrogen halides within the stratosphere correlated to volcanic SO₂. Investigation of the longer-term stratospheric impact of these emissions, using the 3D chemical transport model, SLIMCAT suggests that volcanic enhancements of H₂O and HNO₃ increased HNO₂ 3H₂O particle availability within the plume. These particles activated volcanic HCI and HBr, enhancing model plume concentrations of Cl...
