Abstract:
"We used multiple regression analysis to relate
evapotranspiration (ET), computed from a water balance technique, to both
thermal infrared and normalized difference vegetation index data obtained from
the Advanced Very High Resolution Radiometer (AVHRR) sensor on board on the
National Oceanic and Atmospheric Administration ( NOAA) satellite. This
approach, based on only remotely sensed data,
... provided a reliable estimate of
ET over the Pampas, the main agricultural region of Argentina. The relationship
between spectral data and ET was more sensitive to the dates than to the sites
used to generate the models". To access the full text of this article, go to
