Laboratory spectroscopy experiment: Spectral reflectance of beach sand as function of surface moisture content with sample of beach sand collected from the Sand Motor, the Netherlands

Spectral reflectance of beach sand (350-2500 nm) under different moisture conditions at 1 nm interval, obtained by a laboratory spectroscopy experiment. Optical remote sensing has the potential to measure surface moisture at a high spatio-temporal resolution. It is based on the principle that wet sand appears darker than dry sand: it is less reflective. The goals of this study are (1) to measure and model reflectance under controlled laboratory conditions as function of wavelength ( ) and surface moisture ( ) over the optical domain of 350–2500 nm, and (2) to explore the implications of our la...
