The variation of the directional reflectance of a vegetative canopy with azimuthal view angle becomes prominent when the canopy is illuminated by the sun at large angles from zenith. An extension of a previous directional reflectance model of vegetative canopies is presented to quantify this effect. The results indicate that the cause of the azimuthal variation can be traced to solar flux illum...

server products to provide interoperability between desktop personal computers (PCs) running the Microsoft Windows operating system and remote hosts running the X Window System operating system under the UNIX or OpenVMS operating systems. The first version of the eXcursion X server was a 16-bit application written specifically for Microsoft Windows versions 3.0 and 3.1. As the popularity of Win...

The purpose of this study is to indicate several areas of interest within the Yahoo! Messenger application that are of forensic significance. This study will mainly focus on new areas of interest within the file structure of Windows Vista and Windows 7. One of the main issues with this topic is that little research has been previously conducted on the new Windows platforms. The previously condu...

Linear polarization of the clear daytime sky has often been measured as a spectrally integrated or quasi-monochromatic variable, but seldom as a spectral one. So we use a hyperspectral imaging system to measure skylight polarization at high spectral and angular resolutions for clear and hazy skies at our coastal site. The resulting polarization maps and spectra exhibit both commonalities and di...

The validation of ocean color satellite retrievals generally relies on analyzing match-ups between in situ measurements and retrievals. These analyses focus the quality data, however, same importance is data. Here, we present spatial variability above-water reflectance (R rs (0+)) within resolution different satellites—300, 900, 1500, 3000 m resolutions, mimicking Sentinel 3 OLCI MODIS-Aqua sat...
