- Description
- In order to investigate the spectral behavior of humidity on sand spectra, we have acquirice–gypsum mixtures, we have acquired laboratory reflectance spectra of an icelandic black sand continaing various proportion of water. Water was deposited on a dry sand (previously dried in an oven at 40°C during one night). The sample is then dried, under the sun at 38°C. A spectrum is acquired ervery 5 minutes with an ASD FieldSpec3FR in order to investigate the evolution of the spectra with the decreasing of water content.
