                         of the Equatorial Amazon Forest during the dry season, induced by 
                         the greater availability of incoming solar radiation, which 
                         indicates that for most of the region water availability is not a 
                         limiting factor. However, other studies show that the MODIS sensor 
                         registers artifacts due to changes in the solar-zenith angle, 
                         resulting in less shaded fractions in the dry season. This paper 
                         aimed to evaluate the seasonal behavior of the FLONA Tapaj{\'o}s 
                         using MODIS-MAIAC data, in response to water and radiation 
                         availability. Phenology was associated to the NDVI, EVI and to the 
                         shadow, green vegetation and non-photosynthetic vegetation (NPV) 
                         fractions, obtained from the linear spectral mixing model. The 
                         time series were evaluated with the BFAST package. The radiation 
                         had a significant (p-value <0.05) negative correlation with the 
                         soil moisture, besides that vegetation can still have access to 
                         water after rainfall ceases, because soil moisture response has a 
                         lag of two months in relation to rainfall. EVI and NPV presented 
                         positive correlation with the radiation (0.88 and 0.80). The 
                         existence of MODIS artifacts does not fully explain the observed 
                         results, as the shadow fraction does not fall during the dry 
                         months, so that structural changes can occur, coinciding with 
                         studies that observed tree mortality, flushing of leaves and loss
