ARMOR3D: a 3D high-resolution temperature, salinity, mixed layer depth and geostrophic velocities product based on satellite and in situ observations

 ARMOR3D is a 3D product based on a statistical approach that merges satellite and in situ observations to retrieve temperature, salinity, mixed layer depth and geostrophic velocities from 0 to 1500m depth and based on seasonal climatic temperature and salinity from 1500 to 5500m. This product is part of the Copernicus Marine Service catalog (https://doi.org/10.48670/moi-00052) and its resolution has been increased to reach a daily temporal resolution and 1/8° spatial resolution. Here, we’ll present the different steps of the methods used and the main results of the in-depth validation that was carried out on this new high-resolution version. Thermosteric and halosteric trends will be discussed.
