area_fraction_of_day_defined_by_solar_zenith_angle

"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. A coordinate variable of solar_zenith_angle indicating the day extent should be specified. Solar zenith angle is the the angle between the line of sight to the sun and the local vertical.
