Satellite-derived radar and laser altimetry data measures the precise height of the Earth's surface, including oceans, ice sheets, land, and vegetation. It is primarily used to create very accurate digital elevation models, monitor sea-level rise, map ocean circulation, and determine underwater topography.  This session will explore the utility of altimetry alone or with other measurement capabilities to improve stakeholders’ understanding of risk, and improve resilience and adaptation. The session invites contributions that use multisensor approaches that use altimetry data together with spaceborne lidar, optical, hyperspectral and radar to develop decision-making applications and address key challenges that include sea level rise, wildfire risks, hazard assessment, and urban heat planning.
