Abstract

This dataset consists of hourly simultaneous aerosol and cloud optical depth (AOD and COD) retrievals using the Combined Inversion of Surface and Aerosols (CISAR) algorithm applied to observations from the SEVIRI (Spinning Enhanced Visible and Infrared Imager) onboard the MSG1 and MSG4 satellites. It has been produced in the framework of the European Space Agency's (ESA) Climate Change Initiative x-ECV SATACI project.

By leveraging the geostationary viewing geometry of both satellites, the information content is increased, improving the performance compared to a single-view retrieval (Heidinger et al., 2026). This dataset extends the DUST2MSG dataset available on Zenodo (https://zenodo.org/records/8424628) to -10º South and covers the whole year 2020.
