"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. Viewable snow refers to the snow on objects or the ground, viewable from a top view. It excludes snow obscured by plants or other objects and falling snowflakes.

"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. Canopy and surface snow refers to the snow on the vegetative covering over a surface, and for a surface devoid of any vegetative cover to the snow on the ground, but excludes, for example falling snowflakes and snow on the surface obscured by vegetative cover. The canopy is often considered to be the outer surfaces of the vegetation. Plant height and the distribution, orientation and shape of plant leaves within a canopy influence the atmospheric environment and many plant processes within the canopy.

It may be expressed as a fraction, a percentage, or any other dimensionless representation of a fraction. Canopy and surface snow area refers to the snow on objects or the ground as viewed from above, which excludes, for example, falling snow flakes and surface snow obscured by a canopy, vegetative cover, or other features resting on the surface. The canopy is often considered to be the outer surfaces of the vegetation. Plant height and the distribution, orientation and shape of plant leaves within a canopy influence the atmospheric environment and many plant processes within the canopy.

"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. The surface called "surface" means the lower boundary of the atmosphere. Surface snow refers to the snow on the solid ground or on surface ice cover, but excludes, for example, falling snowflakes and snow on plants. "Canopy" means the vegetative covering over a surface. The canopy is often considered to be the outer surfaces of the vegetation. Plant height and the distribution, orientation and shape of plant leaves within a canopy influence the atmospheric environment and many plant processes within the canopy.
