| Zusammenfassung |
| During last year EGU meeting, BIRA-IASB presented early results of a reanalysis of the
stratospheric chemical composition based of assimilation of satellites observations using the
Belgian Assimilation System for Chemical ObsErvations (BASCOE). Presented results were
based on an assimilation of MLS (O3, H2O, HCl, HNO3, ClO) and MIPAS (CH4,
N2O, NO2, N2O5, ClONO2, CFC-11, CFC-12) for 2008. This year contribution
will present the latest improvement achieved including the extended period (May
2007 to Dec 2010). As done last year, the quality of the analyses will be discussed
using comparison against ozonesondes and ACEFTS data. We will also discuss
the ability of the system to produce useful analyses in the following stratospheric
conditions: polar winters (i.e. denitrification, dehydration, chlorine activation and ozone
destruction), polar winters perturbed by descent of mesospheric NOx, and the UTLS. |
