ASSIMILATION OF STRATOSPHERIC OZONE FROM MIPASIN THE CHEMICAL TRANSPORT MODEL STRATAQ

摘要

We use a sequential assimilation approach to assimilaternozone MIPAS profiles into the STRATAQ chemicalrntransport model of the stratosphere. The numerical codernuses parameterizations and simplifications allowingrnassimilation of sparse observations and the simultaneousrnevaluation of analysis errors. The CTM used is a highrnresolution three dimensional model which includes arndetailed chemical package and is driven by UKMOrnanalysis. Two weeks of MIPAS ozone measurementsrnare assimilated during October 2002, and resultsrnvalidated using data from the SAFIRE-A instrumentrnwhich is part of the M-55 Geophysica platform operatedrnduring the APE-ENVISAT airborne validationrncampaign.
