Application of the kinetic theory of partly ionized gases to radiation transfer and ionization in hydrogen nebulae
… into a singular part corresponding to “direct” radiation from the star, and a non-singular part corresponding to “diffuse” radiation. The concept of statistical equilibrium is applied to the electron population to provide an auxiliary equation, and the Stromgren equation derived as an …

Detailed thermal analysis of a thin-shell, spherical radiometer in Earth orbit
… balance is conducted on a spherical thermal radiation detector. The thermal radiation heat transfer to the spherical detector is computed utilizing models of the surface optical properties that vary with surface temperature, wavelength and angle of incidence. Studies have been conducted to …

Solar energy as a renewable resource for cooling
… while it has been found that the solar diffuse radiation factor ‘C’ (C=Gdh/Gbn) actually not constant but varies all through the day in a typical way; The turbidity factors are lower in 2010 during winter time due to usage of cleaner fuels and district heating while during summer they …

Constraining the UV background with the proximity effect
… level by the cosmic UV background radiation field. Primarily composed of the integrated contribution of quasars and young star forming galaxies, its intensity is subject to spatial and temporal fluctuations. In particular in the vicinity of luminous quasars, the UV radiation …

Assessing solar radiation components over the alpine region Advanced modeling techniques for environmental and technological applications.
… for estimating the spatial distribution of solar radiation, and in particular its diffuse and direct components in mountainous regions. The study area is the Province of Bolzano (Italy). The motivation behind this work is that radiation components are an essential input for a series of …

Analysis of the "nurse-tree effect" of exotic shelter trees on the growth of the indigenous Podocarpus falcatus in an Ethiopian montane forest
… climate, the efficacy of the shares of the irradiation from diffuse light and light flecks were determined from light curves. The time spans and distribution of these shares of the daily accumulated radiation were recorded from the daily courses. In the Pinus plantation, the efficiency of the …
