Description
The ALTIUS instrument observes the atmosphere in several modes: limb scatter, solar/lunar and stellar/planetary occultation. Furthermore, Level 2 data delivery splits in two separate lines: a near real-time ozone product and a collection of offline scientific products. Both aspects lead to a data processing chain that is a bit more complex than is usually the case. In this overview, we will present the Level1 processing from raw to geolocated and calibrated data, and the subsequent Level 2 processing to gas concentration and aerosol extinction profiles for each observation mode separately, highlighting the main physical/mathematical aspects that need to be taken into account. The current status, ongoing work and unresolved issues will also be discussed.
