Wave and wind along-track altmetry products (level3) NRT
Along-track significant wave height (SWH) and wind speed modulus for the following missions : CFOSAT (nadir), Sentinel-3A, Sentinel-3B, Jason-3, Saral-AltiKa, Cryosat-2 and HY-2B in Near-Real Time (NRT) for a global coverage (-66°S/66+N for Jason-3, -80°S/80°N for Sentinel-3A and Saral/AltiKa). SWH measurements are computed from the leading edge of the altimeter waveform. For Sentinel-3A and 3B, they are deduced from the SAR altimeter. One file containing valid SWH is produced for each mission and for a 3-hour time window. It contains the filtered SWH (VAVH), the unfiltered SWH (VAVH_UNFILTERED) and the wind speed (wind_speed).
