A global daily mesoscale front dataset from satellite observations

A global daily mesoscale front dataset based on ESA CCI SST dataset spanning from 1982 to 2023

Our global front dataset from 1982 to 2023 is archived in NetCDF format under the variable name “front”, comprising 15,340 individual daily files. The daily “front” variable is stored as a two-dimensional numerical matrix with dimensions of 7200 in the zonal direction and 3600 in the meridional direction. The values of the “front” variable are unitless, where regions with values greater than 0 represent the warm sides of detected frontal zones, while those with values less than 0 indicate the cold sides. All positions where the “front” variable equals -10, 10, or 30 correspond to detected frontal lines, with these values respectively indicating frontal lines near cold sides, warm sides, and no-front zones.
