NASA-ISRO Synthetic Aperture Radar (NISAR)

NISAR will enhance our understanding of how changes in Earth’s forest and wetland ecosystems affect the worldwide carbon cycle and contribute to climate change.

Key Highlights:

• NISAR is a joint effort by NASA and ISRO, operating in Low Earth Orbit (LEO).
• NISAR features both L-band and S-band synthetic aperture radar (SAR) instruments, making it the first satellite to use two different radar frequencies.
• SAR can operate day and night, penetrating clouds, and adverse weather conditions.
• Mission Objectives: Monitoring Earth Changes: NISAR’s primary goal is to measure changes in Earth’s ecosystems, surfaces, and ice masses, offering insights into biomass, natural hazards, sea-level rise, and groundwater.
• Global Observation: The satellite will globally monitor land and ice-covered areas with a 12-day revisit frequency in both ascending and descending passes.
