SWOT Level 2 Nadir Altimeter Interim Geophysical Data Record with Waveforms - SGDR
Listed in NASA Earthdata CMR
Same as L2_NALT_GDR, using preliminary values for some auxiliary data.
Description
Uses Medium-accuracy (preliminary) Orbit Ephemeris (MOE). Available with latency of < 1.5 days.
Discrete measurements at nadir for each half orbit, along the ground track. Available in netCDF-4 file format. This collection is a sub-collection of its parent: podaac.jpl.nasa.gov/dataset/SWOT_L2_NALT_IGDR_2.0
