• A low reflectance value that occurs once or twice a day indicates an anomalous attenuation of<br />
the signal coming <strong>from</strong> that point. In most cases these values are caused by shadowing. It could<br />
also be extinction by absorbing aerosols, but these aerosols would most likely have a darkening<br />
effect on the surface reflectance of adjacent pixels and observation times as well. The overall<br />
methodology is questionable there.<br />
