                         pixels from Modis images to be used in monitoring coffee plots. 
                         Time series of EVI and NDVI were assessed only for those Modis 
                         pixels selected according to the described procedure. A 
                         wavelet-based filter was used to smooth NDVI and EVI time 
                         profiles. Additionally to the single value analysis of vegetation 
                         indices we derived a range value of vegetation index in each year 
                         through the difference of maximum and minimum vegetation indices 
                         inside the growing season. Coffee plots present maxima and minima 
                         EVI/NDVI at the end of rainy and dry seasons in Brazil 
                         respectively. Yet minima values agree to post-harvesting period 
                         when plots lose leaves due to mechanic damage caused by 
                         harvesting. The range of vegetation indices in each year showed an 
                         alternate pattern, that is, a greater fall in vegetation indices 
                         followed by a smaller fall the next year and again a greater fall 
                         the following year. Such a behavior suggests great and small fall 
                         of leaves in alternated years and can be associated to trends in 
                         coffee yield. We will include yield data obtained from farmers to 
                         evaluate if the magnitude of defoliation, assumed to be reflected 
                         in vegetation indices, is related to coffee yield.",
