Remotely sensing plant canopy water status remains a long term goal of remote sensing research. Established approaches to estimating canopy water status - the Crop Water Stress Index, the Water Deficit Index, the Equivalent Water Thickness and the many other indices - involve measurements in the thermal or reflective infrared. Here we report plant water status estimates based upon analysis of polarized visible imagery of a cotton canopy measured by Ground Multiangle SpectroPolarimetric Imager (GroundMSPI). Such estimators potentially provide access to the plant hydrological photochemistry that manifests scattering and absorption effects in the visible spectral region.ISSN
