sea_ice_area_with_sea_ice_area_fraction_above_threshold m2 [UMSQ]
"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. Sea ice area fraction is area of the sea surface occupied by sea ice. It is also called "sea ice concentration". "Area fraction" is the fraction of a grid cell's horizontal area that has some characteristic of interest. It is evaluated as the area of interest divided by the grid cell area, or if the cell_methods restricts the evaluation to some portion of that grid cell (e.g. "where sea_ice"), then it is the area of interest divided by the area of the identified portion. It may be expressed as a fraction, a percentage, or any other dimensionless representation of a fraction. The value is equal to the sea_ice_area where sea_ice_area_fraction is above the threshold. Otherwise, the value is zero.

Otherwise, the value is zero. 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.
