2023年7月16日 · To investigate sensitivity and quantify biases of incorporating hyperspectral albedo information into ESMs, we examine how shortwave soil albedo affects surface radiative forcing and simulations of the carbon and water cycles.

Soil albedo values for various soil surfaces. When modeling the soil/atmosphere interaction, it is of paramount importance to determine the net radiation flux. There are two common...

2019年3月19日 · In this study, we used multiyear 500 m albedo products from the Moderate Resolution Imaging Spectroradiometer (MODIS) to derive the bare soil albedo for seven spectral bands and three broadbands over the contiguous United States (CONUS).

2009年2月1日 · The albedo of the soil/litter substrate, referred to as the soil background albedo, is derived from partially vegetated regions using a method that separates the vegetation contribution to the albedo signal from that of the soil/litter substrate.

2022年6月15日 · Increasing the albedo of cropland could enhance reflection of solar radiation, counteracting the radiative forcing (RF) of greenhouse gases (GHGs) and local warming. However, knowledge is lacking on how agricultural practices affect albedo under local conditions, and on the benefits of individual practices.

2018年7月31日 · Understanding the relationship between the surface albedos in different wavebands, and soil moisture will provide theory basis for the parameterization of surface albedos.

The objectives of this study were (1) To determine empirical relationships between smooth bare soil albedo and soil color, (2) To develop statistical relationships between albedo and ground-based thematic mapper (TM) measurements of spectral reflectances, (3) To determine how increased surface roughness caused by tillage reduces bare soil ...

2018年4月12日 · Compared with previous studies, this new physically based parameterization scheme of soil albedo has two main features: (i) the α s is estimated as a function of μ and w soil, and the relationship between the α s and w soil is exponential, and (ii) the parameter values are estimated using the transfer equation proposed in this study, which ...

2005年12月22日 · The most significant factors affecting the soil albedo are the type and condition of the vegetation covering the soil surface, soil moisture content, organic matter content,

2000年5月1日 · The 0.3- to 2.8-μm albedos of smoothed soils can be accurately estimated using the regression relationship: soil albedo (0.3–2.8 μm) = 0.069 (color value) − 0.114. Using the regression equations presented here, spectral reflectance data in selected visible and NIR bands can also be used to predict albedo.
