             abstract = "The objective of the study was to describe seasonal phenological 
                         profiles by means of the vegetation index and investigate the 
                         seasonal evapotranspiration cycle of sugarcane areas in the 
                         municipality of Barretos, S{\~a}o Paulo, by applying harmonic 
                         analysis to time series of EVI and evapotranspiration from 
                         products of the MODIS/Terra sensor. We used a 2-year time series 
                         of EVI data (16 days) and ET data (8 days) for the years 2010 and 
                         2011. The vegetation presents seasonal and periodic behaviour; the 
                         harmonic analysis expresses the periodic phenomenon in a series of 
                         sinusoidal and cosinusoidal functions described in amplitude and 
                         phase values, from which we can extract the variance of each term 
                         in the data set. In the sugarcane area that presents annual 
                         seasonality, the majority of the variance was captured by the 
                         second harmonic, with vegetative vigour between the months of 
                         January and April. The additive term, the amplitude and the phase 
                         angles enable us to identify, respectively, the areas of lesser 
                         and greater vigour, the periodicity of events, and the period of 
                         maximum vegetative vigour. The study demonstrated the utility of 
                         the analysis for detecting areas of change in the vegetation, such 
                         as reform and expansion of sugarcane areas, showing potential for 
                         monitoring and analyzing landscape changes, with reduction in the 
                         data volume of temporal data series.",
