THE INTERFERENTIAL STUDY OF THE DIRECT SOLAR RADIATION
DURING THE PERIOD OF THE INTERNATIONAL GEOPHYSICAL YEAR

Valeria Winter

Abstract

On basis of the average values of the intensity of the direct solar radiation, measured by means of interferential filters in the framework of the International Geophysical Year, the author establishes the average values of the Angström parameters for Bucharest during that period, as well as their correlation with the meteorological factors.
The determinations were occasionally influenced by the sources of additional nuclei existing in the vicinity of the site of observations.
