NISAR Status
•Work on radar antenna
reflector for satellite is
nearing completion i
•Launch readiness date TBD
when reflector is returned to
India and reintegrated with
radar system

2024-Feb 2025 due to Sun’s
position
•First light images 2-3 months
after launch
•Science operations 3 months
after launch
•Global products to Level 2 will
be fully and openly available
to the global community
•See

Products for Science and
Applications
•Response of ice sheets to climate change and
the interaction of sea ice and climate
•Carbon storage and uptake dynamics in
wooded, agricultural, wetland, and permafrost
systems
•Earthquake, volcanic, and landslide cycles,
exploring potentials for urgent response and
hazard mitigation
•Soil Moisture
•Dynamics of water, hydrocarbon, and
sequestered CO
2
reservoirs
•Supports dozens of applications
•12-day repeat orbit, ascending and descending
•Global Analysis Ready Synthetic Aperture
Radar Data –
•Geocoded, terrain corrected, polarimetric
products

21. Early Adopters and Community of
Practice
are individuals or organizations that can be public or private, Federal or local entities,
and can have a local, national or international scope for their application.
Community of Practice
Early Adopters
are individuals and organizations who
•have a clearly defined need for NISAR data
•have an existing application that can benefit from
NISAR and
•are capable of applying their own resources to
demonstrate the utility of NISAR data for their
application.
Early Adopters provide important feedback to the NISAR
team regarding which NISAR data products meet the
needs of their applications.
