The 3-day gridded datasets are produced from the Lagrangian products described elsewhere in this website (Lagrangian Overview). Parameters from the Lagrangian dataset are processed to produce fields with constant grid spacing. The gridded parameters are: ice age, ice thickness, backscatter histogram, multiyear ice fraction, divergence, vorticity and shear. Data values cover a 3-day period on a 12.5 x 12.5 km grid. Each of the downloadable files contains one month of these 3-day product files.
