Item #d95mar8

"Ozone Profiles at McMurdo Station, Antarctica, During the Spring of 1993; Record Low Ozone Season," B.J. Johnson (Dept. Atmos. Sci., Univ. Wyoming, Laramie WY 82071), T. Deshler, R. Zhao, Geophys. Res. Lett., 22(3), 183-186, Feb. 1, 1995.

Total column ozone declined by 55% from an initial 275 Dobson Units on Aug. 30, to a minimum of 130 7 DU on Oct. 2. Probable causes of this record low ozone concentration, based on balloon-borne observations at McMurdo Station include: the presence of Mt. Pinatubo aerosol; a colder than normal stratosphere over McMurdo; and a relatively stable polar vortex which delayed intrusion of high levels of ozone from outside its wall.


Item #d95mar9

"Interhemispheric Differences in Polar Stratospheric HNO3, H2O, ClO, and O3," M.L. Santee (Jet Propulsion Lab., MS 183-701, 4800 Oak Grove Dr., Pasadena CA 91109), W.G. Read et al., Science, 267(5199), 849-852, Feb. 10, 1995.

Measurements of these substances were obtained over complete annual cycles by the Microwave Limb Sounder on the Upper Atmosphere Research Satellite. Arctic O3 depletion was substantially smaller than in the Antarctic. A major factor currently limiting the formation of an Arctic ozone hole is lack of denitrification in the northern polar vortex. Future cooling of the lower stratosphere could lead to more intense denitrification there.
