dc.description.abstractIt has been studied statistically the incidence of solar radio flux fluctuations in nearly 1000 hr of continuous observations at 7 GHz, and shown that some tropospheric phenomena can be analysed by this method. Of the fluctuations 93 per cent were coincident with the presence of CL clouds whose borders seem to be the major factors responsible for reflecting a portion of the incoming rays, producing interference fringes at the observer's site. Absorption effects were also sometimes observed, and small effects in polarization were qualitatively characterized. Such events could be easily confused with the "fluctuation" type solar bursts, and the present results emphasize the need of improved criteria for the analysis of very small solar events, that do exist at microwave wavelengths. Further work was developed on steady troposphere attenuation at larger zenithal angles, and on ground contribution at solar onset times. © 1969.
