"\"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. Fog means water droplets or minute ice crystals close to the surface which reduce visibility in air to less than 1000m."@en . "3" . "3" . . "false" . "" . "fog_area_fraction"@en .
