This work was aimed at investigating the effectiveness of genetic algorithms (GA) - partial least square (PLS) regression in estimation of canopy equivalent water thickness (EWT) from MODIS image data of the SMEX'04 site. Calibration of MODIS spectral variables (single bands, band ratios and curvatures) against the AVIRIS-derived EWT at a degraded resolution resulted in a high correlation (R2=0.77)...
