3. Answer: D

Explanation:

What is NISAR?

• ISRO and Jet Propulsion Laboratory (JPL)/ NASA are jointly working on the development of Dual Frequency (L & S band) Synthetic Aperture Radar Imaging Satellite named as NASA-ISRO Synthetic Aperture Radar (NISAR)
• The L-band SAR is being developed by JPL/NASA, while ISRO is developing S-band SAR
• The L & S band microwave data obtained from this satellite will be useful for variety of application
• Applications:

• Natural resources mapping & monitoring
• Estimating agricultural biomass over full duration of crop cycle
• 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.
• Identifying crevasses in the glaciers hidden by fresh snow, where human movement takes place
• Identifying the snowpack parameters as an input in Avalanche forecasts
• Studying Glacial Lake Outburst Floods (GLOF) hazards
• Identifying inundated area due to floods/ cyclones
• The data obtained from NISAR mission is not meant for building climate resilience
