1.8 CF Standard Names: Stratiform Cloud Area Fraction in Atmosphere Layer (stratiform_cloud_area_fraction_in_atmosphere_layer)

Record Label : stratiform_cloud_area_fraction_in_atmosphere_layer

Record Title : Stratiform Cloud Area Fraction in Atmosphere Layer

CF Standard Name : stratiform_cloud_area_fraction_in_atmosphere_layer

Record Description : "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. 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. In an atmosphere model, stratiform cloud is that produced by large-scale convergence (not the convection schemes). Cloud area fraction is also called "cloud amount" and "cloud cover".
