                         Hyperion multitemporal data. The study area was selected in the 
                         Tapaj{\'o}s National Forest located in Par{\'a} State, Brazilian 
                         Amazonia. The region has well-defined dry and wet seasons with 
                         yearly rain about 2,100 mm a dry season occurring from June to 
                         October. The study area is primarily covered by dense tropical 
                         rain forest (Floresta Ombr{\'o}fila Densa) with a high number of 
                         emergent tree species. The EO-1 Hyperion data were acquired in 
                         July, August and September 2001, corresponding to the dry season 
                         in this region. The Linear Spectral Mixing Model was applied on 
                         each calibrated surface reflectance data, generating vegetation, 
                         soil, and shade fraction images. Then fundamental statistical 
                         analyses were carried out to evaluate the differences within the 
                         vegetation and shade fraction images derived from medium spatial 
                         resolution Hyperion images for rainforest phenology analysis.",
