TerraSAR-X (TSX), TanDEM-X (TDX), and PAZ Synthetic Aperture Radar data have been used at over 120 volcanoes to assess surface characteristics change time. We examine previous work, adding additional examples understand where when these are most useful for volcanology. focus on as part of the Committee Earth Observation Satellites (CEOS) Volcano Demonstrator Project. TSX/TDX/PAZ provide a valuable means detecting small changes from amplitude images topographic bistatic TSX/TDX data. For short temporal perpendicular baselines, TDX/TSX/PAZ can also deformation data, even in presence vegetation. No global background mission currently acquires volcanoes: 70 % high spatial resolution limiting their suitability studying pre-eruptive unrest. Coordinated targeting by SAR constellations priority would insights forecasting eruptions associated hazards.
