Multi-sensor Aerosol Product from EPS-SG – Consideration for the Operational Aerosol Product

With the launch of EPS-SG in 2025, EUMETSAT will operate a space platform hosting a series of instruments among which VII, 3MI, IASI-NG and UVNS (Sentinel-5). The potential of a synergistic approach combining 3 instruments has been already demonstrated with the release of the EPS/PMAp product, operational as a Near-Real-Time aerosol product since 2014. After a colocation of all the measurements provided by the instruments, the synergistic retrieval becomes possible. For EPS-SG, an important step forward will be made with the polarimeter 3MI which will allow the provision of many aerosol properties. The synergistic use of the other instruments will contribute to improve this characterisation from 3MI. The spectral extension to UV and TIR, the sub-pixel information, but also the use of absorption bands. The pre-design of this synergistic product will be presented.
