Abstract

The moisture content of forest fuel on the forest floor is a determining factor in assessing the ignition and spread of fire. The measurement of moisture content through indirect methods benefits obtaining and visualizing results immediately. Some indirect methods are based on the measurement of environmental variables, but they require calibration for specific tree data. In this work, we examine the diffuse reflectance spectra of the leaves of different tree species in two spectral bands, obtaining a relationship with the measurement of the moisture content of the leaves through the indirect method based on meteorological factors. This relationship contributes to the characterization of remote sensing devices implemented in measuring moisture content in biomass dry on the forest floor, improving measurement accuracy.
