                         occurrence of 255 standard fill value pixels in Collection 4 MODIS 
                         LAI product (MOD15A2) and the soybean areas in Rio Grande do Sul 
                         State, Brazil. Time series of 8-day composite LAI product images 
                         and 16-day composite NDVI images were referenced to a soybean map 
                         produced over Landsat images in order to analyze the influence of 
                         soybean areas in the occurrence of 255 standard fill values pixels 
                         as well as in the LAI algorithms performance, throughout the crop 
                         season. Besides, a biome classification map (MOD12Q1 Landcover 
                         product) was also analyzed to verify whether the occurrence of 
                         those pixels is related to a biome-type misclassification. The 
                         results indicate that the Standard fill value 255 retrievals in 
                         Collection 4 LAI product are closely related to the soybean areas 
                         and their occurrence appears not to be directly related to an 
                         eventual misclassification in biome map input. Therefore, the 
                         Collection 4 MOD15A2 product is not suitable to monitor LAI 
                         seasonal changes over soybean areas.",
