Vis-NIR reflectance spectra of Narbonne sand (NS 264) wetted with water and dried in ambiant air at 38°C

Véronique Carrère
In order to investigate the spectral behavior of humidity on sand spectra, we have acquired laboratory reflectance spectra of a sand containing various proportion of water. Water was deposited on a dry sand (previously dried in an oven at 40°C during one night). During the experiment, the sample is then dried, under the sun at 38°C. A spectrum is acquired every 5 minutes with an ASD FieldSpec3FR. This experiment was done on Narbonne sand (NS...
