Either filter transmittance, filter reflectance or a combination of transmittance and reflectance is measured. Typically, one would like to know the reflectance and transmittance of the layer structure. The peak reflectance wavelength increases for smaller incident angles. A related material property is reflectivity (also called "reflectance"). Soil organic carbon is mainly derived from proximal sensing using mid infrared reflectance. As the surface reflectance or optical thickness increase, the degree of polarization decreases. BDRF can facilitate translations of observations of reflectance into albedo. Another parameter controlling the overall reflectance is surface roughness. And let P be the Planar Albedo, which represents the total reflectance from the scene. Deriving an inter-sensor consistent calibration for the AVHRR solar reflectance data record. Lidar produces plant contours as a "point cloud" with range and reflectance values. This reflectance gives chlorophyll its green appearance. ASTER data is used to create detailed maps of land surface temperature, reflectance, and elevation. The nape is yellow and attracts the attention of the parents by its ultraviolet reflectance. Freshly fallen snow and charcoal are approximately Lambertian surfaces of high and low reflectance respectively.
