Sentinel-6B/Jason-CS L1A P4 Altimeter High Resolution (HR) STC Intermediate Outputs with Instrument CalibrationsProvides L1A high resolution (HR) short time critical (STC; 36-hour latency) altimetry intermediate outputs from the Poseidon-4 SAR altimeter on the Sentinel-6B spacecraft, which are geo-located bursts of Ku-band echoes (at ~140 Hz) with all instrument calibrations applied and full rate complex waveforms for delay/Doppler or HR processing. The S6B STC product is analogous to the Jason-3 IGDR produ

SWOT Precise Orbit Ephemeris (POE)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.

SWOT Satellite Reconstructed Attitude DataSatellite attitude reconstructed from combination of onboard gyro and star tracker data. Daily 26-hour files centered at 12:00:00 (TAI) provide quaternions to represent the rotation between the spacecraft body-fixed KaRIn Metering Structure Reference Frame and the inertial Geocentric Celestial Reference Frame. Available in netCDF-4 file format with latency of < 1.5 days.
