This dataset correponds to a 1ox1o of gridded diffusivity coefficients (in m2 s-1). It is a global coverage at 1000-m depth. This diffusivities are computed using local-analog method based on deep Argo float trajectory from the  ANDRO dataset. The ANDRO dataset used in this study corresponds to the 2019 Release (key: 66657) and is freely available through the SEANOE  platform ( The dataset provide longitudes and latitudes and the zonal, meridional, and cross diffusivity coefficients.
