Abstract

The objective of this study was to evaluate satellite remote sensing to estimate evapotranspiration (ET) for olive orchards in Tunisia. Crop water stress index (CWSI) and reference or actual ET were estimated for treatments having deficit drip irrigation at 60, 50 and 40% of crop ET. Results showed significant differences in CWSI or ET between treatments. ET estimates from satellite imagery were strongly correlated with ground truth measurements, with r2 values of 0.86 and 0.62 for potential ET and actual ET, respectively, showing that satellite imagery can accurately quantify spatial and temporal patterns in ET in Tunisian olive orchards.
