ARMOR3D (product ID MULTIOBS_GLO_PHY_TSUV_3D_MYNRT_015_012) is a global L4 ocean-physics analysis product distributed by the Copernicus Marine Service. It delivers daily, gap-free three-dimensional fields of ocean temperature, salinity, absolute dynamic topography (sea surface height), geostrophic current components, and mixed-layer depth on a regular 0.125-degree global grid extending through 50 depth levels from the surface to the bottom.^[1]^[2]

The product is generated by CLS (Collecte Localisation Satellites) using an optimal interpolation scheme that merges satellite altimetry sea-level anomalies with in situ temperature and salinity profiles from Argo floats, moorings, and ship-based measurements, together with a background climatology.^[2] Sea-level anomaly observations draw on satellite altimetry; the product incorporates multiple concurrent altimetry missions.^[1]

Two time-series variants are provided: a near-real-time (NRT) stream updated daily, and a reprocessed multiyear (REP) record. Both are distributed free of charge under the Copernicus Marine Service open-data licence and are accessible via the CMEMS data portal. The current product operates at 0.125-degree horizontal resolution; an earlier archived predecessor used 0.25-degree resolution.^[1]^[3]
