Description

Precise Orbit Ephemeris (POE) providing position and velocity vectors of satellite center of mass used in the first SWOT reprocessing. POE products are organized into daily files, spanning 26 hours and centered at 12:00:00 (TAI) of each day (i.e., from day D-1 23:00 to day D+1 01:00 TAI time). Available in netCDF-4 file format with latency of < 35 days.
