Definition
- "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. 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.
Note
