Description
BIRA-IASB is involved in data assimilation (DA) of stratospheric chemical observations since almost 20 years. This is done though the development of the Belgian Assimilation System of Chemical ObsErvations (BASCOE). In this presentation, we will discuss the capabilities of DA methods to validate (1) the measurement concept of ALTIUS and (2) the ALTIUS observations.
For the first case, an Observing System Simulation Experiment (OSSE) of ALTIUS ozone data has been performed based on a BASCOE analysis of the Microwave Limb Sounder. With this OSSE, we will evaluate the measurement concept of ALTIUS (limb and occultations – solar, stellar, planetary and Moon), especially during the polar night where limb observations are missing.
In the second case, we will describe the ALTIUS level 3 data product – i.e. the ALTIUS analysis by BASCOE that will be delivered operationaly – and how this product will be useful to validate ALTIUS level 2 profiles.
