GRIB:

Fraction of time steps which had sea ice during the averaging period of typically one month. It allows one to differentiate half a month of 100% sea-ice cover from a full month of 50 % sea-ice concentration.

"X_area_fraction" means the fraction of horizontal area occupied by X. Sea ice area fraction is area of the sea surface occupied by sea ice. The area threshold value must be specified by supplying a coordinate variable or scalar coordinate variable with the standard name of sea_ice_area_fraction. "Sea_ice" means all ice floating on the sea with the exception of floating ice shelves, which are regarded as land ice in models.

"X_area_fraction" means the fraction of horizontal area occupied by X. Sea ice area fraction is area of the sea surface occupied by sea ice. The area threshold value must be specified by supplying a coordinate variable or scalar coordinate variable with the standard name of sea_ice_area_fraction. "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.
