The proposed NASA-ISRO Synthetic Aperture Radar (NISAR) Mission, a collaboration between the National Aeronautics and Space Administration (NASA) and the Indian Space Research Organization (ISRO) would acquire radar images of surface changes globally. Radar penetrates clouds and operates day and night. It produces images that are detailed enough to see local changes, and has broad enough coverage to measure regional trends. Rapid sampling over years to decades would allow for understanding disturbance, degradation, and response. NISAR's unprecedented coverage in space and time would reveal forces acting within the Earth and on its surface and variability in ice masses and biomass far more comprehensively than any other measurement method. The detailed observations would reveal information that would allow us to better manage resources and prepare for and cope with global change.
