Spectral index selection method for remote moisture sensing under challenging illumination conditions (2022)
Journal Article
Graham, C., Girkin, J., & Bourgenot, C. (2022). Spectral index selection method for remote moisture sensing under challenging illumination conditions. Scientific Reports, 12(1), Article 14555. https://doi.org/10.1038/s41598-022-18801-9

Remote sensing using passive solar illumination in the Short-Wave Infrared spectrum is exposed to strong intensity variation in the spectral bands due to atmospheric changing conditions and spectral absorption. More robust spectral analysis methods,... Read More about Spectral index selection method for remote moisture sensing under challenging illumination conditions.
