abstract = "Amongst several existing vegetation indices, NDVI Normalized
Difference Vegetation Index is the most famous one. Its
applications range from crop monitoring to surface emissivity
estimations. Although NDVI provides several benefits on
highlighting vegetation features, it is also affected by image
characteristics and atmospheric composition. Due to the importance
of normalized vegetation indices to various fields of study, the
present research seeks to detect and to evaluate the effects of
atmospheric correction on NDVI values retrieved from Sentinel-2
images over distinct land cover classes. Scenes with
top-of-atmosphere and bottom-ofatmosphere reflectance were
selected, and a 6S atmospheric correction algorithm was applied to
generate a third dataset (116 images each). NDVI was calculated
and the mean of each scene was evaluated to seven land cover
classes, including vegetation, urbanization and water-covered
areas. The results showed that atmospheric correction increases
NDVI in vegetation areas, while dunes, urban and watercovered
surfaces presented the largest errors.",
