NISAR Science Users’ Handbook – “The NASA-ISRO Synthetic Aperture Radar (SAR), or NISAR mission is a multi-disciplinary radar mission to make integrated measurements to understand the causes and consequences of land surface changes. NISAR will make global measurements of the causes and consequences of land surface changes for integration into Earth system models. NISAR provides a means of disentangling and clarifying spatially and temporally complex phenomena, ranging from ecosystem disturbances, to ice sheet collapse and natural hazards including earthquakes, tsunamis, volcanoes and landslides. The purpose of this handbook is to prepare scientists and algorithm developers for NISAR by providing a basic description of the mission and its data characteristics that will allow them to take full advantage of this comprehensive data set when it becomes available…”
