We present two 2-meter Digital Elevation Models (DEMs) of Mount Etna obtained from tri-stereo Pléiades images acquired on 24 December 2015 and 18 July 2016. The 3D processing of the Pléiades imagery was performed using the free and open source MicMac photogrammetric library (http://micmac.ensg.eu) developed by the French IGN (Institut Géographique National).The covered area is almost the same for both the DEMs (about 15 × 15 km) and includes the summit area of Etna volcano and almost all the Valle del Bove area. The presented DEMs are not aligned, but after co-registration, the standard deviation of their height difference was found equal to ∼1.6 m (in an area not covered by volcanic deposits emplaced on May 2016). The DEMs are provided as GeoTIFF raster (dem20151224_2m.tiff and dem20160718_2m.tiff), using the WGS84 datum and the UTM projection, zone 33 North (EPSG 32633). Missing areas are due to snow cover, very low texture and/or terrain shadows.Pléiades data were available through the Space Volcano Observatory with Pléiades (SVOP) project coordinated by Pierre Briole (http://volcano.iterre.fr/svo_projects). We are grateful to Olivier Galland, Luc Girod and Christopher Nuth for their assistance with the use of the MicMac software. This work was developed within the framework of the Laboratory for Technological Advance in Volcano Geophysics (TecnoLab) of the INGV in Catania (Italy) and was partially supported from the "Advanced tools and methods for computational fluid-dynamics"(ATHOS) research programme.
