X"_binary_mask" has 1 where condition X is met, 0 elsewhere. The value is 1 where the ice cover area fraction is greater than a threshold, and 0 elsewhere. The threshold must be specified by associating a coordinate variable or scalar coordinate variable with the data variable and giving the coordinate variable a standard name of surface_ice_area_fraction. The values of the coordinate variable are the threshold values for the corresponding subarrays of the data variable.

"Sea ice" means all ice floating in the sea which has formed from freezing sea water, rather than by other processes such as calving of land ice to form icebergs.
