  abstract = {{R}emote sensing data are a key tool to assess large forested areas, where limitations such as accessibility and lack of field measurements are prevalent. {H}ere, we have analysed datasets from moderate resolution imaging spectroradiometer ({MODIS}) satellite measurements and field data to assess the impacts of the 2005 drought in {A}mazonia. {W}e combined vegetation indices ({VI}) and climatological variables to evaluate the spatiotemporal patterns associated with the 2005 drought, and explore the relationships between remotely-sensed indices and forest inventory data on tree mortality. {T}here were differences in results based on c4 and c5 {MODIS} products. {C}5 {VI} showed no spatial relationship with rainfall or aerosol optical depth; however, distinct regions responded significantly to the increased radiation in 2005. {T}he increase in the {E}nhanced {VI} ({EVI}) during 2005 showed a significant positive relationship ({P} < 0.07) with the increase of tree mortality. {B}y contrast, the normalized difference water index ({NDWI}) exhibited a significant negative relationship ({P} < 0.09) with tree mortality. {P}revious studies have suggested that the increase in {EVI} during the 2005 drought was associated with a positive response of forest photosynthesis to changes in the radiation income. {W}e discuss the evidence that this increase could be related to structural changes in the canopy.},
