article i nfo Binary snow maps and fractional snow cover data are provided routinely from MODIS (Moderate Resolution Imaging Spectroradiometer). This paper investigates how the wide observation angles of MODIS influence the current snow mapping algor

Realistic simulation of on- and off-road vehicle performance in all weather conditions is needed by the U.S. Army for virtual training of personnel on existing vehicles, and for new vehicle design. The virtual test site is a computer simulation repre

Forest canopies influence the proportion of the land surface that is visible from above, or the viewable gap fraction (VGF). The VGF limits the amount of information available in satellite data about the land surface, such as snow cover in forests. E

High-resolution ground vehicle mobility models are used by the U.S. Army to investigate new vehicle concepts, conduct force-on-force simulations, and–in the future–support terrain analysis for battle planning. Use of these models in winter condit

Solar radiation beneath a forest canopy can have large spatial variations, but this is frequently neglected in radiative transfer models for large-scale applications. To explicitly model spatial variations in subcanopy radiation, maps of canopy struc

Energy budget dynamics under forest canopies are strongly influenced by the large spatial variability of radiative and turbulent transfers in this environment. Incoming solar radiation under canopies has a particularly high degree of spatial variabil

Up-looking solar and atmospheric radiation sensors at remote and quasi-remote weather stations are typically intermittently covered by snow in the winter. Numerous years of radiation data compromised in this way have been collected and archived at th

The fraction of the surface under forest canopies that is visible from above, or the viewable gap fraction (VGF), influences a number of significant physical processes, such as the longwave radiation budget of the surface and the magnitude of diffuse

A new model is presented for simulating snow surface albedo in the open and beneath a mixed-forest canopy. The model has modest input data requirements and is an efficient physically based parameterization that includes the dependency of albedo on so

Despite the importance of litter on forest floor albedo and brightness, previous studies have not documented forest floor albedo or litter cover in any detail. Our objective was to describe the seasonal influence of litter on spectral albedos and nad
