######### data description #########


1. weekly landfast ice extent dataset from 1976-2026

2. the weekly data was stored in a bin file with binary format.

3. the file "north_x_y_lat_lon.txt" was the grid information.

4. the matlab code file "contour_weekly_extent_code.m" was used to plot weekly bin file.
