Sentinel-6A MF Jason-CS L1A P4 Altimeter High Resolution (HR) NTC Intermediate Outputs with Instrument Calibrations

(JASON_CS_S6A_L1A_ALT_HR_NTC_F)
DOI10.5067/S6AP4-1AHNT
Short NameJASON_CS_S6A_L1A_ALT_HR_NTC_F
DescriptionProvides L1A high resolution (HR) non-time critical (NTC; 60-day latency) altimetry intermediate outputs from the Poseidon-4 SAR altimeter on the Sentinel-6A Michael Freilich 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 S6A NTC product is analogous to the Jason-3 GDR product.
