Summary of research for FY-1995: Progress report
The object of this proposal is to study the reduction in mid-latitude stratospheric ozone and to estimate the budget of tropospheric ozone. The product of this proposal include: (1) the estimation of dilution of air masses processed by polar stratospheric clouds inside the polar vortex during winter; and (2) the destruction of ozone via heterogeneous reactions on the surface of aerosol particles which are present at all latitudes, especially after large volcanic eruptions such as Mt. Pinatubo; (3) to quantify photochemical production and destruction of O{sub 3} in the free troposphere; (4) to quantify export of ozone from polluted to remote regions, and (5) to quantify cross-tropopause exchanges of O{sub 3} and other species. The approach of this proposal is to use and to improve the two-dimensional and three-dimensional global chemical/dynamical models.
