Model simulations of stratospheric ozone loss caused by enhanced mesospheric NO x during Arctic Winter 2003/2004
International audience Satellite observations show that the enormous solar proton events (SPEs) in October?November 2003 had significant effects on the composition of the stratosphere and mesosphere in the polar regions. After the October?November 2003 SPEs and in early 2004 significant enhancements...

International audience Satellite observations show that the enormous solar proton events (SPEs) in October?November 2003 had significant effects on the composition of the stratosphere and mesosphere in the polar regions. After the October?November 2003 SPEs and in early 2004 significant enhancements of NO x (=NO+NO 2 ) in the upper stratosphere and lower mesosphere in the Northern Hemisphere were observed by several satellite instruments. Here we present global full chemistry calculations performed with the CLaMS model to study the impact of mesospheric NO x intrusions on Arctic polar ozone loss processes in the stratosphere. Several model simulations are preformed with different upper boundary conditions for NO x at 2000 K potential temperature (?50 km altitude). In our study we focus on the impact of the non-local production of NO x which means the downward transport of enhanced NO x from the mesosphere in the stratosphere. The local production of NO x in the stratosphere is neglected.
