The weekly analysis grids are given in standardized binary data format (Network common data form: NetCDF v4). The variables are given as grid arrays, see therefore Table 1. All grids are projected onto the 25 km EASE2 Grid, which is based on a polar aspect spherical Lambert azimuthal equal-area projection (Figure 1). NetCDF files are formatted according to CF conventions: CF-1.6 ACDD-1.3.
