A new spectrophotometer for measuring ultraviolet sky brightness and direct solar radiation, final scientific report, 1 Jan.-31 Dec. 1966 by Paul Bener( Book )

2 editions published in 1967 in English and held by 5 WorldCat member libraries worldwide

A transportable spectrophotometer for measuring ultraviolet sky brightness and solar radiation from 295 to 400 millimicrons is described. This instrument serves for a study of atmospheric scattering by comparing measured and theoretical values of intensity. Its main components are: A double monochromator Zeiss MM 12, a telescope, a photomultiplier enclosed in a cooling box and a mounting for following the sun and scanning the sky according to the astronomical and horizontal system respectively. Neutral attenuation filters are applied to bridge the interval of brightness (100,000) between sun and sky and to adapt the sensitivity to the varying sky brightness. The components of sky brightness polarized parallel and normal to the entrance slit are measured separately. An effective spectral bandwidth between 0.9 and 2.5 millimicrons is normally applied. Mean values of the signal current are measured by means of a Keithley 610 A electrometer and a voltage-to-frequency converter. Photon counting is applied for the lowest levels of intensity. The overall accuracy amounts to plus or minus 7% for intensity and to plus or minus 3% to 5% for the ratio between sky brightness and solar radiation

The diurnal and annual variations of the spectral intensity of ultraviolet sky and global radiation (between 297.5 mu and 380 mu) on cloudless days at Davos, 1590 m.a.s.l by Paul Bener( Book )

1 edition published in 1963 in English and held by 3 WorldCat member libraries worldwide

The climatological features of the spectral intensity of ultraviolet sky and global radiation are presented in this paper in the form of hourly values for every month of the year. These figures relate to monthly means of atmospheric ozone and to average conditions of ground reflexion and turbidity during the ''winter period'' (ground covered with snow) and the ''summer period'' (ground free from snow). Diagrams showing the diurnal variation of the intensity for various wavelengths and its spectral distribution for different hours of the day are presented for December, March, June and September, which months have high, medium and low monthly means of atmospheric ozone amount. Further diagrams show the annual variation of the intensity for various hours and wavelengths. The latter curves illustrate the combined effect of the annual variation of solar declination, atmospheric ozone and ground reflexion on the intensity of ultraviolet sky and global radiation. The ratio between the vertical component of direct ultraviolet solar radiation and total diffuse radiation is examined in its diurnal and annual variation and in dependence on wavelength. An increase of this ratio with in creasing values of solar altitude and wavelength can be stated for all wavelengths between 330 mu and 370 mu. The influence of atmospheric ozone on this ratio is shortly discussed

Approximate values of intensity of natural ultraviolet radiation for different amounts of atmospheric ozone : final technical report by Paul Bener( Book )

1 edition published in 1972 in English and held by 1 WorldCat member library worldwide

The present report deals with the results of measurements and computations of ultraviolet sky, solar, and sun+sky (global) intensity for 15 wavelengths between lambda = 297.5 and 380 nm and for 12 values of total amount of atmospheric ozone covering the interval of 0.240 to 0.460 cm in increments of 0.020 cm. The variation of ultraviolet intensity in dependence on Northern Latitude and season and the influence of an assumed reduction of atmospheric ozone is examined. The variation of the short wavelength limit of the terrestrial solar spectrum is furthermore discussed. The results on ultraviolet intensity for selected values of ozone and solar altitude are presented in tables. Diagrams demonstrate the variation of global intensity in dependence on the principal parameters. The present data are based on the results of extensive measurements of ultraviolet sky intensity at Davos, Switzerland (1950 m a.s.l.), and completed by a theoretical computation of direct solar intensity for elevations of 0 to 5 km s.s.l
