Explanation:

ISRO and Jet Propulsion Laboratory (JPL)/ NASA are jointly working on the development of Radar Imaging Satellite named as NASA-ISRO Synthetic Aperture Radar (NISAR).
• The L & S band microwave data obtained from this satellite will be useful for variety of application, which include natural resources mapping & monitoring; estimating agricultural biomass over full duration of crop cycle etc.
• It also includes assessing soil moisture; monitoring of floods and oil slicks; coastal erosion, coastline changes & variation of winds in coastal waters; assessment of mangroves; surface deformation studies, ice sheet collapses & dynamics etc.
• These applications could help in taking measures to minimize loss of human lives.
