Decision

What the current evidence supports

Human editorial judgment · 2026-06-28

Proceed with caution

Why
Mission is live and openly delivering L-band data with strong specs (24/9.4 cm dual band, 3-10 m resolution, 747 km / 98.4 deg orbit, 12-day repeat with ~6-day revisit), but NASA/ASF itself flags current products as pre-calibration with enumerated defects and an incomplete distortion-correction chain.
Next
Prototype against the pre-calibration L-band L1-L3 / L2 GUNW products now, but gate any production deformation/biomass product on the ~July 2026 fully-calibrated release; track the ASF NISAR Data User Guide known-issues notes for resolution of the rubbersheeting and geolocation defects.
