Sentinel-6B/Jason-CS L2 P4 Altimeter High Resolution (HR) NRT Ocean Surface Topography
Listed in NASA Earthdata CMR and NASA Data Portal — shown once because both records carry DOI 10.5067/s6bp4-2hsnr
Provides L2 high resolution (HR) near real time (NRT; 3-hour latency) altimetry from the Poseidon-4 SAR altimeter on the Sentinel-6B spacecraft.
Description
It contains Sea Surface Height (SSH), Sea Surface Height Anomalies (SSHA) and Significant Wave Height (SWH), along with 1 Hz and 20 Hz Ku-band measurements processed from L1B altimetry including the range, orbital altitude, time, and water vapour. It also includes altimetry corrections, significant wave height and wind-speed from the AMR-C. This standard product release provides the geophysical parameters at both 1 and 20 Hz.
The S6B NRT product is analogous to the Jason-3 OGDR product.
