SWOT Medium-accuracy Orbit Ephemeris (MOE)

Published by Jet Propulsion Laboratory;NASA/JPL/PODAAC | National Aeronautics and Space Administration | Catalog Last Checked: June 25, 2026 at 01:53 PM | Dataset Last Updated: June 23, 2026
Medium-accuracy Orbit Ephemeris (MOE) providing position and velocity vectors of satellite center of mass used in forward stream processing. MOE 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 < 1.5 days.
