Non-operational MIPAS and SCIAMACHY profiles

The Southern Hemisphere Vortex split of Sep/Oct 2002:
From ENVISAT MIPAS and SCIAMACHY spectral data of the period 18 Sep to 13 Oct global stratospheric temperature fields and trace gas distributions of the species O3, CH , N2O, HNO3, NO , NO, CFC-11, ClONO2, N2O5, and H2O were retrieved. The data sets show the split-up of the Southern polar vortex which is most pronounced on 25 to 27 Sep and its re-formation in October. Each data set is characterised by random error, vertical resolution, the number of independent data points per profile, a measure of the contribution of a priori knowledge to the data point presented.

The Arctic Winter 2002/03
Under TOPOZ-III, vertical profiles of a number of atmospheric trace species and temperature/pressure were retrieved with the science-oriented MIPAS level-2 data processor developed at IMK and IAA. Vertical profiles of O3, NO2, BrO and OClO were retrieved with the scientific SCIAMACHY algorithms developed at UBRM. The retrievals are based on level 0 and level-1b data product provided by ESA.

A detailed description can be found in the"; target="_blank">Deliverable Report 1.3.

The data is used within the project by partners of WP2. They validate and improve the chemical transport models by comparison of the ENVISAT data with model results.

The main innovatives are the new quality and coverage of data of atmospheric trace constituents by ENVISAT.
