It is evaluated as the area of interest divided by the grid cell area. It may be expressed as a fraction, a percentage, or any other dimensionless representation of a fraction. \"Layer\" means any layer with upper and lower boundaries that have constant values in some vertical coordinate. There must be a vertical coordinate variable indicating the extent of the layer(s). If the layers are model layers, the vertical coordinate can be \"model_level_number\", but it is recommended to specify a physical coordinate (in a scalar or auxiliary coordinate variable) as well. Standard names also exist for high, medium and low cloud types. Standard names referring only to \"cloud_area_fraction\" should be used for quantities for the whole atmosphere column. Cloud area fraction is also called \"cloud amount\" and \"cloud cover\"."@en ; sdo:inDefinedTermSet ; sdo:name "ice_cloud_area_fraction_in_atmosphere_layer"@en ; sdo:termCode "SDN:P07::95JF7EN0" .
