simulation of stratospheric ozone in response to the increased surface CFCs emissions

摘要

To evaluate the stratospheric process in the response to the increased surface CFCs emissions, some simulations were carried out by the NCAR interactive chemical, dynamical and radioactive two-dimensional (SOCRATES) model. The investigation showed that when the surface CFCs emissions increased by 30%, these chemical components would be transported into the stratosphere and would play an important roles in stratospheric chemistry and radiation. In the layers from 40km to 48km, the relative variety of active component was ClOx by 20% , HOx by -2% , NOx by -2% and 03 by -5%, respectively. At the same time, temperature reduced by 0.6K.
