Off-nadir Angles – Sentinel-3 Altimetry Technical Guide – Sentinel Online
The off-nadir angles are computed at Level-2 processing.
- Square of the WF-derived off-nadir angle (Ku band) is issued from the ocean retracking in LRM/PLRM modes and from the ocean/coastal retracking in SAR mode. It accounts for modelled instrumental errors correction and system bias.
- Square of the WF-derived off-nadir angle validity flag (Ku band)
- Square of the WF-derived off-nadir angle (Ku band) validity flags
- RMS of the square of the WF-derived off-nadir angle (Ku band)
- Number of valid points for the square of the WF-derived off-nadir angle (Ku band)
- Modelled instrumental correction on the square of the WF-derived off-nadir angle (Ku band)
- PF-derived off-nadir pitch angle
- PF-derived off nadir roll angle
- PF-derived off-nadir yaw angle
