Abstract: To establish under what condition silicon cells can be used for the determination of albedo, measurements as well as calculations were undertaken. The results show that silicon cells (also sold as Sol-A-Meters) give ?true? ...

Abstract: The ratio of diffuse irradiance to direct normal is a conserved quantity throughout the day. Though its absolute value depends on the condition of the atmosphere, ground reflection and obstruction of horizon, once this ...

Abstract: Spring snowcovers exhibit a substantial contribution of a specular component to their reflection of solar radiation. This anisotropy can be measured with radiometers with small aperture, here with a TIROS radiometer. ...
