    • Sentinel-6A MF Jason-CS L2 P4 Altimeter Low Resolution (LR) NRT Ocean Surface Topography

    Metadata Updated: March 12, 2026

    Provides low resolution (LR) near real time (NRT; 3-hour latency) measurements of sea surface height anomaly (SSHA), Significant Wave Height (SWH), and Wind Speed, along with 1 Hz and 20 Hz measurements from the radar altimeter, orbit altitude, environmental range corrections, instrument corrections, and geophysical models. The NRT product is analogous to the Jason-3 OGDR product.
