Remote sensing of fuel moisture content from ratios of narrow-band vegetation water and dry-matter indices

► Fuel moisture content (FMC) is the ratio of water content to dry-matter content. ► Hypothesis: estimate FMC using ratios of spectral water to dry-matter indices. ► Relationships between FMC and ratios of spectral indices were non-linear. ► Best dry-matter spectral index is based on a CH stretch overtone at 1722 nm.
