The authors confirm that all data underlying the findings are fully available without restriction. Surface moisture is an important supply limiting factor for aeolian sand transport, which is the primary driver of coastal dune development. As such, it is critical to account for the control of surface moisture on available sand for dune building. 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.
Encyclopedia of Planetary Science pp Cite as. The amount of light scattered by substances in bulk mass form changes with wavelength. At wavelengths visible to the human eye, this phenomenon is the basis for the perception of color. These spectral variations are caused by wavelength-dependent absorption, and can be used to infer such properties of the material as composition and electronic or molecular structure. As with gases, the absorption usually occurs in discrete bands, the exception being metals, which absorb over a broad range of wavelengths. For this reason the bands usually overlap, complicating their recognition and producing a continuum of absorption.
Description Reflectance and emittance spectroscopy are increasingly important tools in remote sensing and have been employed in most recent planetary spacecraft missions. They are primarily used to measure properties of disordered materials, especially in the interpretation of remote observations of the surfaces of the Earth and other terrestrial planets. This book gives a quantitative treatment of the physics of the interaction of electromagnetic radiation with particulate media, such as powders and soils. Subjects covered include electromagnetic wave propagation, single particle scattering, diffuse reflectance, thermal emittance and polarisation. This new edition has been updated to include a quantitative treatment of the effects of porosity, a detailed discussion of the coherent backscatter opposition effect, a quantitative treatment of simultaneous transport of energy within the medium by conduction and radiation, and lists of relevant databases and software.

The theory in which either or both reflected sunlight and thermally emitted radiation contribute to the power received by a detector viewing a particulate medium, such as a powder in the laboratory or a planetary regolith, is considered theoretically.

This book is aimed at students and researchers who wish to use reflectance and emittance as quantitative tools to measure the properties of surfaces and materials. It is intended primarily for use in the interpretation of remote observations of the surfaces of the Earth and other planets, and it will also be useful to chemists, physicists, geologists, engineers and others who deal with particulate media. Topics include propagation and absorption of light in continuous media, reflection by smooth surfaces, scattering by spheres and irregular particles, reflectances and emissivities of particulate media, reflectance and emittance spectroscopy, and the polarization of light scattered by particulate media. Many examples of applications are given. Enable full ADS. Citations

Если спасение Сьюзан равнозначно крушению его планов, то так тому и быть: потерять ее значило потерять все, а такую цену он отказывался платить. Хейл заломил руку Сьюзан за спину, и голова ее наклонилась. - Даю вам последний шанс, приятель. Где ваш пистолет.
Джабба почувствовал, что она медлит с ответом, и снова нахмурился. - Ты так не считаешь. - Отчет безукоризненный. - Выходит, по-твоему, Стратмор лжет. - Не в этом дело, - дипломатично ответила Мидж, понимая, что ступает на зыбкую почву.
