abstract = "This work aims at checking for trends in time series of
meteorological and remote sensing data in areas of natural
grassland, located in Depress{\~a}o Central,RS. The analyzed
period was from 04/01/1998 until 12/21/2011. This study used
ten-day period averages of minimum, mean and maximum air
temperature data, ten-day period of accumulated rainfall and
ten-day period of accumulated evapotranspiration data provided by
an automatic weather station, located in Eldorado do Sul-RS
(30º06'20''S, 51º41'10''W). Blue, red, near infrared and
mid-infrared bands and Normalized Difference Vegetation Index
(NDVI) of Vegetation sensor was used. Six areas of native
grassland were identified to be analyzed by the Vegetation sensor.
Plots were constructed to show the dispersion and linear trend
line using Sigmaplot 10.0 software. Correlation analyzes with a
ten-day period lag between the meteorological data and the
Vegetation sensor was performed. The accumulated rainfall was the
only element of climate that tended to increase. The other
meteorological data showed stability during the analyzed period.
For the Vegetation sensor data, the most sensitive bands to
changes in the amount of water in the canopy, as the mid-infrared
and red bands, showed negative trend. This result is consistent
with the increased cumulative rainfall. In correlation analyzes
with a ten-day period lag, the band near infrared and NDVI showed
higher correlation coefficient with the meteorological data.",
