Abstract

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 and the Equivalent Water Thickness-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 Multi-Spectral Polarization Imager (MSPI). Such estimators potentially provide access to the plant hydrological photochemistry that manifests scattering and absorption effects in the visible spectral region.
