ABSTRACT. The potential for monitoring plant water stress in full-canopy cotton using airborne remote sensing was examined in this study. Remote sensing data, using hyperspectral (HSI), multispectral (MSI), and thermal infrared (TIR) sensors, were collected over two seasons on two varieties of Acala cotton and two experimental fields, with a total of nine flights, all with 100% canopy cover. The spatial resolution of the remote sensing data used in the study was near 1.0 m. The TIR camera was used to detect the elevated canopy temperature that occurs when the plants are water stressed. The degree of stress, as measured …
