- Description
- 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 Iceland sand
