SWOT Level 2 Nadir Altimeter Operational Geophysical Data Record with Waveforms - SSHA, Version 2.0

Same as L2_NALT_GDR using predicted values for some auxiliary data, and does not have GIM ionosphere model values. Uses the onboard DORIS orbit ephemeris. Available with latency of < 7 hours. Discrete measurements at nadir for each data downlink, along the ground track. Available in netCDF-4 file format.
