GLOBAL OCEAN L4 SIGNIFICANT WAVE HEIGHT FROM NRT SATELLITE MEASUREMENTS

'''Short description:'''

Near-Real-Time gridded multi-mission merged satellite significant wave height, based on Copernicus Marine level-3 SWH datasets. Only valid data are included. It merges multiple along-track SWH data (Sentinel-6A, Jason-3, Sentinel-3A, Sentinel-3B, SARAL/AltiKa, Cryosat-2, CFOSAT, SWOT-nadir, HaiYang-2B and HaiYang-2C). There are two datasets in the product, the first provides daily gridded data at a 2° horizontal resolution of VAVH_DAILY fields which are daily statistics computed from all available level 3 along-track measurements from 00 UTC until 23:59 UTC. The second, provides VAVH_INST field which is an estimate of the instantaneous wave field every 6h, and 0.5° spatial resolution, using all available Level 3 along-track measurements and accounting for their spatial and temporal proximity.
