Abstract

Impacts of atmospheric halogens on the ozone depletion events (ODEs) in polar boundary layer have been under investigation since the discovery of negative correlation between atmospheric ozone and bromine. By simulating an ODE in a box model KINAL, this study focuses on the influence of natural organic sources on the ozone depletion. An estimation of bromine flux from Arctic plantation is given as 6.3 x 106 molec. Br/(cm2s). Since there exists huge fluctuation in the flux, the bromine input is set to be adjustable, by which the impact of Arctic biological behavior on the tropospheric ozone can be predicted. Meanwhile, another nitrogen flux emitted from plants is also included in the model as the plants release considerable amount of nitrogen into the atmosphere, which alters the process of the ozone depletion. Different from the Br flux, the nitrogen flux implemented in the model remains relatively stable around 1 x 108 molec. NO/(cm2s). The simulation results indicate that the type of the Br flux plays a relatively important role in the depletion of ozone. An average level of Br input may cause approximately a 1.0 day antedate to the ODE. In contrast to that, NO exerts minor impact on the ozone concentration, but an obvious force to the mixing ratio of Br species.
