This document describes the algorithm for retrieving the synergetic lidar/radar/msi classification of the EarthCARE signals. The ATBD is set up according to the EarthCARE ATBD format. This algorithm will ingest Lidar, Radar and MSI data (L1d) as well as their respective target classifications (L2a) data in order to create a combined target mask and classification field. This product will be compatible both in terms of conventions and file format with the L2a Radar-only and L2a-Lidar-only products.
