2. WP3 WP achievements: - Draft of the ATBD for the different MACE input products for some instruments (to be delivered @ T0 + 18) - Selection of the Mt. Etna events for MACE products generation and validation - Preliminary retrieval products for the Etna test case (SEVIRI, MODIS, IASI, RADAR X band) – MACE inputs Issues, problems: - n.a. Status of deliverables: - No deliverables @ T0 + 9 (D3.1, D3.2, D3.3 @ T0 + 18) Plan for the next period (up to the yearly review): - Preliminary integration for 1 or 2 Etna test cases using both satellite and ground measurements

4. WP3 All these events have been characterized by high ash emissions and, for three of them, the volcanic cloud was affected also by significant amounts of water droplets and/or ice. Because the elaboration of the ground based measurements identified for the validation are still ongoing, the MACE team will reserve the option to select also other test cases if considered more interesting for the project.
