  abstract = {{T}he main goal of this research is to develop and to evaluate a relationship established between {N}ormalized {D}ifference {V}egetation {I}ndex ({NDVI}) and crop coefficient ({K}-c) for estimating crop evapotranspiration ({ET}c) of table grapes vineyards ({V}itis vinifera {L}., cvs. {P}erlette and {S}uperior) in the semi-arid region of {N}orthwest {M}exico. {T}wo consecutive growing seasons (2005 and 2006) of continuous measurements of {ET}c with the eddy covariance system were used to test the performance of the {K}-c-{NDVI} relationship. {A}n exponential relation relating {K}-c to {NDVI} ({R}-2 = 0.63) is proposed and tested here as the basis for calculating {ET}c. {T}he obtained results indicate that the {K}-c-{NDVI} approach estimates {ET}c reasonably well over two growing seasons. {T}he root mean square error ({RMSE}) between measured and derived {ET}c from {NDVI} during 2005 and 2006 were respectively about 0.45 and 0.76 mm day(-1). {S}ome discrepancies between measured and simulated {ET}c occurred when {NDVI} saturates at high values, causing the under-estimation of evapotranspiration.},
