abstract = "The aim of this study was to discriminate NDVI/MODIS temporal
profiles of winter cereals cropping areas in Rio Grande do Sul
State in La Niņa, El Niņo or Neutral years. The data set comprised
NDVI/MODIS images, from April to December of the 2000-2012 series.
The mean values of NDVI of winter cereals cropping areas,
identified by crop masking and unsupervised classification, were
used to elaborated temporal profiles of La Niņa, El Niņo or
Neutral years, according to ENSO (El Niņo Southern Oscillation)
episodes in spring (September-October-November) for NOAA. The
results indicated that the mean of NDVI values varied between 0.41
and 0.81, reflecting the differences in sowing period and plant
growth in the regions of Caxias do Sul, Passo Fundo and Santa
Rosa. The NDVI/MODIS profile of La Niņa was distinct in temporal
evolution of vegetation index, in comparison to El Niņo profile.
NDVI/MODIS temporal profile of La Niņa has a delay in initial
increment and lower values of NDVI during the vegetative stage of
winter cereals in Rio Grande do Sul State (June, July, August and
September). In the series analyzed, higher grain yields were
observed in La Niņa years and NDVI temporal profiles indicated the
gradual accumulation of green biomass according to lower air
temperatures during the cycle of winter cereals in study
regions.",
