Land Surface Hot-spot Observed by MODIS Over Central Africa
The hot-spot is the term used to describe the increased directional reflectance that occurs over most land surfaces when the solar and view directions coincide. Under these viewing conditions, shadows cast on the surface are minimized, resulting in increased reflectance. This phenomenon has been observed in laboratory measurements (Sandmeier et al. 1998), airborne data (Vermote et al. 1997) and multi-angular satellite sensor data by systems such as POLDER (Hautecoeur and Leroy 1998).
