SITE:GROUNDREFLECTANCE:SNOWMODIFIER

Specifies ground reflectance multipliers when snow resident on the ground. These multipliers are applied to the "normal" ground reflectances specified in Site:GroundReflectance.

Ground Reflected Solar Modifier

Value for modifying the "normal" ground reflectance when Snow is on ground when calculating the "Ground Reflected Solar Radiation Value" a value of 1.0 here uses the "normal" ground reflectance Ground Reflected Solar = (BeamSolar*CosSunZenith + DiffuseSolar)*GroundReflectance This would be further modified by the Snow Ground Reflectance Modifier when Snow was on the ground When Snow on ground, effective GroundReflectance is normal GroundReflectance*"Ground Reflectance Snow Modifier" Ground Reflectance achieved in this manner will be restricted to [0.0,1.0]
Minimum: 0.0
Default: 1.0

Daylighting Ground Reflected Solar Modifier

Value for modifying the "normal" daylighting ground reflectance when Snow is on ground when calculating the "Ground Reflected Solar Radiation Value" a value of 1.0 here uses the "normal" ground reflectance Ground Reflected Solar = (BeamSolar*CosSunZenith + DiffuseSolar)*GroundReflectance This would be further modified by the Snow Ground Reflectance Modifier when Snow was on the ground When Snow on ground, effective GroundReflectance is normal GroundReflectance*"Daylighting Ground Reflectance Snow Modifier" Ground Reflectance achieved in this manner will be restricted to [0.0,1.0]
Minimum: 0.0
Default: 1.0
