Observed brightness distributions in overcast skies.
Beneath most overcasts, clouds' motions and rapidly changing optical depths complicate mapping their angular distributions of luminance L(v) and visible-wavelength radiance L. Fisheye images of overcast skies taken with a radiometer-calibrated digital camera provide a useful new approach to solving this problem. Maps calculated from time-averaged images of individual overcasts not only show the...
متن کاملUltraviolet Sky Radiance Distributions of Translucent Overcast Skies
The diffuse sky radiation component in the ultraviolet wavelengths is often at least 50% of the global irradiance under clear skies, and is the dominant component of ultraviolet global radiation under translucent overcast skies. The distribution of sky radiance was measured in a rural area and modeled for wavelength bands of ultraviolet-B (UVB, 280-320 nm) and ultraviolet-A (UVA, 320-400 nm). S...
متن کاملOvercast Skies - What Cloud Computing Should Be?
From an consumer perspective the Cloud is opaque. Online storage and the rise of web applications are changing the way users work. There continues though to be no distinction from a user experience point of view between accessing a Cloud-based application and accessing a web application deployed on a classic server. We propose a new paradigm for online application development which takes the be...
متن کاملOvercast sky luminances and directional luminous reflectances of objects and backgrounds under overcast skies.
Two sky luminance distributions are given for overcast sky above snow-covered terrain, and directional luminous reflectance data are presented which were obtained under these skies. Luminous reflectances computed from Krinov spectral reflectance data for a variety of natural terrains measured under overcast are also included.
متن کاملShort-term variability of overcast brightness.
Overcasts seen from below seldom are uniform, unchanging cloud shields, yet little is known about their short-term photometric variability (periods < or = 2 h). Visible-wavelength spectra of daytime and twilight overcast skies measured at 30-s intervals reveal unexpected temporal variability in horizontal illuminance E(v) and zenith luminance L(v). Fourier analysis of these time series shows pe...
