On the reflectance spectroscopy of snow

Web2 de jul. de 2024 · Different materials on Earth’s surface have different spectra because they reflect sunlight in different ways. (Human eyes can distinguish between snow, water, vegetation, and soil based on their color, which is a result of the various wavelengths they reflect.) Earth scientists use reflectance spectroscopy to study rocks, soil, ocean water ... Web10 de ago. de 2024 · Reflectance spectroscopy is a technique for the measurement of reflected electromagnetic radiation of the Sun as a function of wavelength. The fraction of incident solar radiation scattered back to space by a solid or particulate from a planetary surface contains information about the mineralogy of soils and rocks present therein, …
