| 82 | | If covered by snow, the background albedo is calculated in the VIS and NIR wavelengths by the snow module and accounts for snow age and snow density. If not covered by snow, the background albedo is not simulated but prescribed by the parameters '''bgd_reflectance(:,ivis)''' and '''bgd_reflectance(:,ivis)'''. If the background is partly covered by snow, the snow albedo and the background albedo are merged, which allows snow to settle under the canopy, reflecting In deciduous forest, grasslands and croplands, the background albedo is known to be strongly affected by the phenology and senescence of the understory vegetation.
