             abstract = "We investigated the water use of Caatinga vegetation, the largest 
                         seasonally dry forest in South America. We identified and analysed 
                         the environmental phenological drivers in woody species and their 
                         relationship with transpiration. To monitor the phenological 
                         evolution, we used remote sensing indices at different spatial and 
                         temporal scales: normalized difference vegetation index (NDVI), 
                         soil adjusted vegetation index (SAVI), and green chromatic 
                         coordinate (GCC). To represent the phenology, we used the GCC 
                         extracted from in-situ automated digital camera images; indices 
                         calculated based on sensors included NDVI, SAVI and GCC from 
                         Sentinel-2A and B satellites images, and NDVI products MYD13Q1 and 
                         MOD13Q1 from a moderate-resolution imaging spectroradiometer 
                         (MODIS). Environmental drivers included continuously monitored 
                         rainfall, air temperature, soil moisture, net radiation, and 
                         vapour pressure deficit. To monitor soil water status and 
                         vegetation water use, we installed soil moisture sensors along 
                         three soil profiles and sap flow sensors for five plant species. 
                         Our study demonstrated that the near-surface GCC data played an 
                         important role in permitting individual monitoring of species, 
                         whereas the species' sap flow data correlated better with NDVI, 
                         SAVI, and GCC than with species' near-surface GCC. The wood 
                         density appeared to affect the transpiration cessation times in 
                         the dry season, given that species with the lowest wood density 
                         reach negligible values of transpiration earlier in the season 
                         than those with high woody density. Our results show that soil 
                         water availability was the main limiting factor for transpiration 
                         during more than 80\% of the year, and that both the phenological 
                         response and water use are directly related to water availability
